mutter not only causes problems with realvnc -for which you have a test in your startup script-, but also other VNC server stuff like x11vnc.

The easiest workaround for someone wanting to run that would be "sudo apt remove mutter"
But right now that also uninstalls raspberrypi-ui-mods because you list mutter as depends in debian/control.
I don't see any hard requirement on mutter in this package since you test for the existence of /usr/bin/mutter in your script though, so can mutter be made a Recommends instead?

A few days back I had an issue with desktop not loading keyboard strike rate/delay until user manually launches 'lxinput'.
Similarly, the WM doesn't respect any mouse cursor he may have selected until 'lxappearance' is launched manually.
Even then it keeps reverting back to a the default every few minutes.
Now I understand that lxappearance doesn't appear anywhere in preferences personalization (it did in 32 bit, but unselected).
So the question is, is lxappearance supported at all? If yes, can you please enable it in prefs and fix the aforementioned defect?
TIA

On a fresh raspbian install, Zip files should be automagically associated with the archiver GUI. Current clicking on a zip files brings up a 'what do you want to open this' style dialog.

Hardcoded names for both the "Run..." and "Shutdown..." menu items should be removed from the custom lxpanel profile config file.

Instead, the default "Run" and "Logout" lxpanel menu entries (see lxpanel-buster plugins/menu.c) should be modified/localised through the lxpanel po file.

I don't quite understand Debian configurations, but I think this might be happening during gsettings set lines in postinst which are about some screensaver settings.

Earlier issue at pi-gen: RPi-Distro/pi-gen#102

Hi,

I am not sure if this is correct place and appropriate to ask but is it possible to release .svg formats of PiXflat (and old PiX) icons instead of .png? I am trying to do some additional custom icons myself via inkscape but it is being struggling to edit/create some stock icons to inherit less to gnome icon set. if icons were released in .svg format that would be perfect :)

and lastly, is it possible to maintain old PiX theme too? it feels a bit buggy. some bars and menu items go unscaled sometimes. I know it is old theme but blue theme is good to have with old PiX icons to make desktop retro-ish look.

best regards.

Hope this is the right place for the bug.

I just booted a completely new Noobs image, ran a dist-upgrade and removed three applet icons from the LXPanel Application Menu. The panel then disappeared altogether and I have not seen it since.

Fortunately I already had a terminal open, so I was able to attempt some things. Killing the lxpanel process and relaunching it with the same command line as the original process (same profile) didn't cause it to reappear. Rebooting the machine also didn't cause it to reappear.

Without LXPanel visible, there are no obvious means of running applications at all, not even LXPanel.

This is an extremely serious bug as changing the icons in the Application Menu it's a likely first step for someone launching the Raspbian desktop and it has been immediately and completely fatal to the use of the desktop, meaning I will probably be forced to reinstall NOOBS.

WORKAROUND

I have been able to right-click on the desktop, then choose in one of the tabs an option like 'make Window Manager menus appear when desktop is clicked' (this original set of tabs is now inaccessible). This config change caused a new menu to appear on desktop-click, which includes a 'Terminal Emulator' launch entry.

Running the Terminal Emulator, I can see through ps aux | grep lxpanel that indeed lxpanel --profile LXDE-pi is running, but remains invisible.

Launching the regular lxpanel I get a visible menu at the bottom which is usable, but overall this is very problematic and means there is something seriously wrong with the behaviour of the lxpanel in its normal profile configuration, at least on first boot.

Menu icon does not show in task bar, though it does function. startlxde, NOT startlxde-pi. Mouse over Menu location causes a small icon frame to be dispalyed.

Last good lxde desktop I have is 2019-09-26-raspbian-buster, however when I do an 'apt-get upgrade' it breaks. Icon file is there and is referenced by the task bar. Newer Raspian releases have the issue without any apt-get update.
Issue happens on main X display and on remote xserver-xephyr (remote access from another PI or Debian PC). Happens on remote Xephyr desktop wether if Pi is configured for local desktop or not.
Don't know about realvnc, I purge that when building the PI.
This happens on Pi3, PiZero, and Pi4
No apparent error messages.

The Programming-->Geany Programmer's Editor menu item remains even after removing geany with apt. Is it possible for the menu item to also be removed when geany is removed?

This is on stretch running headless / cli only. (Though a kivvy app starts x from rc.local but without a window manager).

Looks like the upgrade iterates for all users on the system.

In this case, the user was added manually (adduser....) and only logs in via ssh - so they do not have a .config directory or .theme directory to back up anyway.

Process seems to fail on chown oldconffiles directory (which doesn't exist for this user).

The Network Preferences doesn't allow you to specify a hidden SSID, making connecting very difficult.

After selecting SSID, the list only includes "non hidden" SSID's (or nothing if there are no other SSIDs) and it's not possible to specify a SSID if you're trying to connect to a hidden network.

There should be an option to select "Other network" and then specify the SSID manually.

Hello,

I've been directed over here with my issue from StackExchange question and Mutter GitHub.

In Raspberry Pi OS Bullseye, which uses Mutter as default Windows Manager, I noticed that Alt+Tab key combination switches only between current and previously focused windows, i.e. when I have 3 windows open in order A, B, C then I can switch only between B and C, while A stays in the background. So when I need to switch to window A, I need to grab a mouse to change focus.

Is there a way to configure this behavior somehow to be able to switch through all open windows, in a more "classical" way? If so, how can I do that, otherwise is there a chance such configuration could be added or the default behavior changed?

Please note that an "application switcher" of any sort (usually in a form visual overview of all open windows when pressing Alt+Tab and keeping Alt pressed) is completely secondary for me, personally. For productivity reasons I just prefer to be able to switch through more than 2 most recent windows with Alt+Tab.

The StackExchange question mentioned above proposes a workaround: switching Window Manager to Openbox, which seems to have worse performance than Mutter :(.

Thanks in advance.

As noted in a misplaced and closed ticket from @mintslice, the Network Preferences don't allow a hidden SSID to be specified, making connection very difficult.

The panel's list only includes any broadcasted SSIDs without an option to specify a hidden one, as commonly used by many security-conscious LAN owners.

There should be an option to select "Other network" and then specify the SSID manually.

(was Adding Desktop Pager removes ability to switch/move/resize/close windows · Issue #1336 · raspberrypi/documentation, but noted it was in the wrong place.

Actions in desktop:

1. right click in the menu bar, “Add/Remove panel items”

2. in Panel Preferences click “Add”, then select “Desktop Pager” and “Add”.

3. Right-click on newly-created one-page pager, and choose “Desktop Pager Settings”. Add a number (> 1) in the Desktops tab.

4. Close settings.

Expected result: use desktop as normal, but with multiple workspaces.

Actual result: multiple workspaces are enabled, but the ability to switch/move/resize/close windows is lost. The only way to switch/manipulate windows is through right clicking the window indicator in the top bar.

This may be an issue with obconf writing unexpected values into the user's desktop configuration. Seems to be a recent issue, perhaps since Stretch. Didn't appear to be an issue around 2015. Not a stock/upstream LXDE user issue, either: I'm a long-time Lubuntu user and I can add many workspaces without problems. Seems also to be a problem on Raspberry Pi Desktop (for PC and Mac) too.

forum reference: https://www.raspberrypi.org/forums/viewtopic.php?f=116&t=251268

Update: as noted by user petr2 here, creating workspaces via obconf does not cause this problem to appear.

I use multiple workspaces because I have attention deficit/sensory problems, and one workspace per task allows me to focus.

yea i know but you use arch btw, well i cant find any repo/AUR/pkg or someone whom done this before, i really like the DE but the installation process is bad just like arch but worse, can any one point me to the source file so i can compile it or some thing, and whats the apt repo try to install it on a clean debian install but count find the dam repo, i really like your DE thou it lightweight and its built on lxqt.
BTW i use your PC 32bit ver of the raspbian os for my media server is not bad at all very lightweight and easy to maintain.
yes i had to use the BTW is use

Hi.

I love how Pixel theme looks so clean and minimal on RaspiOS so i am trying to add pixel desktop theme and icons to a normal linux distro on my old laptop (32bit debian 11 bullseye) & desktop pc (64bit debian 11 bullseye) but failing to get exact same look. also panel items such as bluetooth and wireless & wired network settings ..etc dont appear.

What packages do i need to install on another linux distro for Raspberry Pi - Pixel desktop theme?

Is it possible for you to add Readme or installation notes please?

thanks.

If a user uses an account that is not named "pi", none of the Pixel UI changes get applied to their account.
The main cause of this is "pi" being hard coded into debian/raspberrypi-ui-mods.postinst.

There are a number of reasons ranging from security to simply a family with multiple kids, why an owner may have more than 1 account on their Raspberry Pi.

It would be great if the code in raspberrypi-ui-mods.postinst could run on all non system user accounts on the Pi, as it can't be assumed everyone uses the "pi" user account.

Recently I observed 2 updates, which informed me about changes that caused obsolete old configuration to be moved to the oldconffiles folder. After the 2nd update i went to the oldconffiles and i see an issue in the behaviour of the postinst routine. It does not check for previous backups existence, and may unconditionally overwrite the backups.

The only point where the existence of oldconffiles is checked, where the OWNER is set:
raspberrypi-ui-mods.postinst line 81

Also i noticed a .desktop file that should show some dialog and remove itself.
Because i have not logged into the desktop after the first update, the content of the file was doubled, looking like the routine that generating it did not overwrite, but appended the dektop entry instead

When Chromium works, it creates on the SD card BrowserMetrics à 4MB files. When Rapsberry Pi is used in Kiosk mode, just writing these files serves negigible purpose but damages the SD card long term. As outlined at https://bugs.chromium.org/p/chromium/issues/detail?id=1171536 the BrowserMetrics files could be disabled by using --disable-features=PersistentHistograms, but for end users like me no additional information is provided and putting --disable-features=PersistentHistograms has not helped.

Please extend Raspberry Pi OS, or the corresponding website, with information how to disable the generation of the BrowserMetrics files, so that running Raspberry Pi with Chromium in Kiosk mode can ensure long file of the SD storage.

I do not know where to fill this, hence it comes here.

Steps to Reproduce:

1. In lxinput, change keyboard delay & interval.
2. Log Off.
3. Log back in.
   Note that the delay & intervals behaviour hasn't changed.

Bug/Feature: It appears that the personalised settings are not loaded when the user logs in.
Workaround: Just launch 'lxinput', and cancel out.

Clicking on PCManFM from desktop shortcut, causes following sequence of events.

2019-09-26-raspbian-buster and 2020-08-20-raspios-buster-armhf images are OK until after apt-get upgrade
Issue happens on main X display (if pi configured to boot with one) and on remote xserver-xephyr (remote access from another PI or Debian PC. Not tested from Windows Cygwin xterminal). Happens on remote Xephyr desktop whether Pi is configured to run a local desktop or not.
Don't know about realvnc, I purge that when building the PI.
This happens on Pi3. Not tested on PiZero or Pi4

The “Your Raspbian system has been upgraded …” box set up at raspberrypi-ui-mods/raspberrypi-ui-mods.postinst at master · RPi-Distro/raspberrypi-ui-mods line 55 keeps coming back on screens smaller than the zenity window. One has to manually delete the ~/.config/autostart/pi-conf-backup.desktop file to make it stop.

A minor issue, I know, but one that affected me.

Couldn't find the source repository for pix-plym-splash, so putting this issue here as the next best option.

pix-plym-splash unconditionally runs plymouth-set-default-theme -R pix in postinst.
This trashes any preexisting plymouth theme selection. It should not do that.

Package: raspberrypi-ui-mods
Version: 1.20210706
Architecture: armhf
Maintainer: Simon Long <[email protected]>

the buster version lacks the critical update 920c8d4 that keeps all flatpaks and many other apps from showing in applications lists

please update the package for buster armhf/arm64 to include this

When upgrading or installing raspberrypi-ui-mods in a virtual console, it may display the following message:

The desktop has been updated. To apply the updates, please reboot your Pi, and then select one of the options on the Defaults page in Appearance Settings.

Then the install script apparently hangs. There appears to be no way for the user to acknowledge this and continue; seemingly the only option is to interrupt the process, leaving dpkg in a bad state.

The reason for the hang is not obvious unless we switch to the GUI session, and see that an alert has popped up, and that the install script is waiting for the user to dismiss this alert before continuing.

This is not expected behavior from an apt upgrade: most of the interaction happens in the console/terminal session.
Furthermore, this alert doesn't do anything except inform the user, which means there's no real need to interrupt everything (including the rest of what may be a lengthy system upgrade) until the alert is acknowledged. It's a frustrating user experience when using a virtual console.

An ideal fix would be to not fire a GUI alert when running from a virtual console. Regardless, it would also be good to make any such information-only GUI alert fire-and-forget, so that if the user didn't already see the message in the console output, it would be waiting for them in the GUI whenever they return there, and any subsequent upgrades and commands can continue to run. If none of that is acceptable and it's essential to halt everything so that the user acknowledges this message, the user should have the option to do so in the same console where the install/upgrade is running (e.g. by pressing a key), rather than requiring the user to acknowledge it out of band, assuming they even know where to look for it.

Trying to keep this limited to actual contrast issues for @spl237 to look at.

1. Evince (default installed PDF viewer) zoom level drop-down arrow:
   Normal:
   
   Mouse over: (mouse is invisible in grim screenshot)
   
   I think the arrow should be white all the time.
   I am unfamiliar with Evince and actually spent a few moments looking for a way to change the zoom level as I did not notice the grey arrow.
2. Evince floating drop-down list improperly highlights the item under the mouse:
   
   Probably the most cohesive thing to do here is to make the button background color a bit lighter grey when under the mouse pointer.
3. Calendar arrows (to change the month and the year) are grey in normal state and white when under the mouse:
   
   They should probably be white at all times.
4. Unintended color gradients on circular buttons at the bottom of Evince Keyboard Shortcuts window
   

Couldn't find the source repository for pix-plym-splash, so putting this issue here as the next best option.

The pix-plym-splash prerm script removes the plymouth-related options from /boot/cmdline.txt unconditionally, even if the pix theme is not currently in use. This incorrectly disables plymouth if some other theme has been configured. It should not do that.

Hello there, im looking to port Pixel Desktop to Manjaro Distro for PC and ARM, and would love to have sources and understand how its installation works. Would be very cool to make it more popular!

Thanks in Advance!

Tracking down this issue, I found the root cause to be that startlxde-pi overrides any set XDG_DATA_DIRS, removing the additions that /etc/X11/Xsession.d/20flatpak adds.

This change simply keeps any existing XDG_DATA_DIRS, prepending the FKMS directory if needed, and allows the searching of the user-specific Flatpak directories.

Hi,

I don't have a user called pi anymore (due to security reasons). And I guess the package should not assume the existence of such a user anyway.

Hi.
I was wondering if you can help me or at least give me advice. I modify/adaptate your PiX/PiXflat theme for native LXDE/openbox and Xfce on desktop since last year or more. But I noticed some gtk/gnome apps not showing properly.

currently using your theme since Debian 11 and now upgraded to 12 with native LXDE installation. Issues i am having are as following:

Context menu arrow icons dont appear in some GTK apps (such as network-manager-gnome gui and Inkscape - if i set theme to system theme/pixflat). in Debian 11/bullseye i was not having context menu arrow icon problem but problem occured after upgrading to Debian 12/bookworm.

and some gnome apps such as gnome-disk-utility and baobab denying to use PiXflat theme and pushing Adwaita theme. this problem continues since Debian 11.

is there something can be done about Pix and Pixflat themes or can you advice for a fix?

thanks in advance.

Need to install mplayer first

When using mplayer from the command line m will mute the sound but pressing m again does not unmute it. The terminal screen reports mute enabled/disabled but nothing happens to the sound
This used to work on issue previous to stretch, possibly on early Stretch versions.
A possible cause is that mute sets the volume slider on the task bar to zero but unmute does not set it back to the previous value so it could be some sort of interaction with the UI

Unmute works on Lubuntu, here the volume slider does not change on the UI when sound is muted

startlxde-pi ovverides XDG_DATA_DIRS making any previous value gone.
(the problem is also in upstream startlxde in debian but it's not the one used on RaspberryPi OS)

This cause application installed using Flatpak to not be available in the menu.

Source:
https://www.raspberrypi.org/forums/viewtopic.php?t=275001
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=906288

Modifying startlxde-pi to NOT clobber XDG_DATA_DIRS fixes the problem.

Problems encountered:

1. URLs are nearly impossible to read.
2. Text on unfocused windows has poor contrast.
   
   This makes it hard to interact with another program while referring back to a text editor.
   
3. The QT theme matches very well, until you encounter "sort by" bars on lists. Example below is VLC's playlist view. It is impossible to read the white text on the white bar.
   
4. I spotted this black text color on gnome-screenshot
   
5. Very bad contrast on Add/Remove Software program
   

However the issue can be fixed by moving /usr/share/themes/PiX.

This is caused by rpi-ui-mods because if lxpanel is run by itself or run without ui-mods installed, it can add applications fine. Once it freezes on one app, that app can never be added back without causing a freeze again… without really messing around with settings.

I think I would have spotted this years ago if it was always an issue, but it has been this way for most of 2024 at a minimum.

Encountered in Geany:

Encountered in Mousepad:

Encountered in lxtask:

Notably, this seems tied to the GTK theme as QT windows and GTK4 windows are unaffected.

This is an unexpected behavior. It can be avoided but I would still consider it a bug.
