Is there any way to remap the keyboard on the keycodes that are sent to the host? My local machine is Dvorak but the BliKVM sends Qwerty keycodes and doesn't respect the operating system's input setting.

Every other application on the computer correctly 'translates' the dvorak input into the intended characters. BliKVM ignores the OS keymap and I assume sends keycodes directly. If I set the destination computer to Dvorak, there wouldn't be any issue.

Banana Pi has released a wonderful BPI-CM4 hardware module compatible with the Raspberry Pi cm4...

Could you verify if your image works on this device? If not. Would you please consider supporting this nice piece of cm4 hardware as well with your images?

More info: https://wiki.banana-pi.org/Banana_Pi_BPI-CM4#System_image

And on the forum: https://forum.banana-pi.org/t/banana-pi-bpi-cm4-computer-module-with-amlogic-a311d/13390

Thanks!!!

Change /boot/config.txt

dtoverlay=dwc2,dr_mode=peripheral

Then reboot will fix this problem

there is an auth to get to the blikvm , so should have a logout as well.
to clear all the state etc...
Thanks

Hi!

as I can see there is wake-on-lan feature mentioned. So is it possible to wake connected pc and how? or it's about wakig kvm itself?

The shell script to fork the OLED python script doesn't have execute permissions, so systemd fails. There is a way to do exactly what the shell script does via native systemd units as an alternative.

There doesn't appear to be a -I argument to hostname on Arch. ifconfig | sed -En 's/127.0.0.1//;s/.*inet (addr:)?(([0-9]*\.){3}[0-9]*).*/\2/p' will do what you want though.

a great additional feature would be to show the status information that is shown on the front OLED and also the fan status directly on the blikvm/pikvm web interface directly.
So in that case you have the health status of the system also visible while looking at other systems.

开机的时候，发现没响应会多次点击，影响体验。

When using the on screen keyboard have a way to make a string of button presses. so you could do something like CNTRL + ALT + Delete.

Can you add an option to "Press and hold power switch" or "hard power off"? In most ATX systems to turn off the stalled PC i must hold "Power" for at least 3-5 seconds

i'm running blikvm hat with hdmi kvm switch. but no control from blikvm gui available. also there is no ttyUSB0 device appearing once control usb cable connected. is there any tricks like special usb cable or smthg else?

switch working well with remote device and using hardware buttons on it. "link" and "power" led's is on once cables connected.

With the new keyboard layout (with marcos) being a bit bigger (in height), the keyboard is not showing up fully on my screen by default:

Move the default position a bit higher (y-axis).. So it should look something like this by default instead:

When I press 01234 on my 10 Key number pad on my keyboard via the v4 BLIKVM I get 890.\ Other numbers and buttons do other things like left click or nothing at all.

+Reboot option for BliKVM itself
+SSH shell support

As a suggestion. May be add here popup with "Current temp CPU"?

Can't find some strings for localization web UI (third_lib/Multi_language/en.js)

1. Text under username and button text
   

2. Text for popup balloon after login
   

3. Text for popup balloon after no update found
   

4. Button text on warning window for Reset ATX
   

5. Text for titles "Version" and "Build", button text for current version Bli KVM
   

6. Text for new popup with current temp and button text
   

make no sense to restart the GUI to take effect.

Trying to run blikvm (edid for 1080p50hz) with my nuc 12 pro leads to blikvm restart while nuc shutsdown. More over, nuc cannot be started after that with power button. Only psu disconnection helps. Nothing in logs. Sametime blikvm works perfectly fine with other my pc.

Hide the panel so we can get almost 1980x1080 on full-screen mode.

Have a way on the onscreen keyboard and/or on the left side menu to do pre-defined macros, ideally customizable by the end user. Things like pressing Control + Alt + Delete or FN+ F5 for swapping screen outputs.

If /use/bin/blikvm/package.json not exist, can't update.

We have recently ordered 3 BliKVMv4 Allwinner and need to change the USB-Mode to disable mass storage in order to work with Dell Desktop BIOS. Where in the filesystem should we place or can we find the override.yaml to add the following settings:

kvmd:

mouse_alt:
device: /dev/kvmd-hid-mouse-alt
msd:

Thanks a lot!

Per our conversation, in order to support ATX with pikvm software on blikvm v4 hardware, we need something similar to kvmd-msd.sh to support ATX controls.

I have been able to run pikvm software on the blikvm v4 hardware and in order to have MSD support, I'm using the built-in kvmd-msd.sh script from blikvm to make/connect/disconnect the ventoy image to the target system by running the kvmd-msd.sh script in ssh/web terminal.

I am requesting something similar to support ATX as the v4 hardware does not use the same GPIO pins for ATX support in pikvm.

1. Button and warning messages on login form are not translated

2. Buttons on reset confirmation form are not translated

3. Button on version information form is not translated

4. In the /opt/bin/blikvm/third_lib/Multi_language there is a French translation, but it's unavailable in language settings.
5. I have sent you a russian translation, but it's too yet not included

Feature Request: Add a Mouse Polling Rate option, similar to that in PiKVM, for adjusting the polling rate of mouse actions.
Shortening the polling interval can make mouse movement smoother.

Here's the option in the PiKVM, the option in PiKVM is actually an interval time, the smaller the value, the higher the polling rate.

ref: https://github.com/pikvm/kvmd/blob/988a190957a367ed7a4b177b428507135d37709c/web/share/js/kvm/mouse.js#L115

in the settings when I choose 16:9 (or another ratio) to match my screen - this setting is reset if there is a timeout (sleeping tab) or you refresh the UI for any reason.
As you are not switching Hosts, we should be able to save these settings so that they stay on refreshes/reboots.

save settings for all settings, or persist the video settings would be nice!

Hi,
It is possible to add one feature to transfer common files (maybe with max. filesize) from client computer to kvm/server computer and vice-versa.
I am looking for files with avg. size of 5MB.
I think that sometime you need to transfer some files or softwares you need to install on machine and this feature is very usefull.
Thank you !

ERROR --- Can't read fan state: Cannot connect to unix socket /run/kvmd/fan.sock

When trying to use a BliKVM v4 connected to a Hikvision NVR I can see the video output of the NVR and while the mouse/keyboard works, the local client mouse position is totally off compared to the remote pointer. It's only correct when the local mouse is positioned to the very top-right corner of the screen.

I note that PiKVM docs talk about mouse modes (https://docs.pikvm.org/mouse/), but I cannot see any mention of that in the BliKVM v4 docs. I've ssh'ed into the KVM but /etc/kvmd doesn't exist.

Tried in Firefox and Chrome. Same problem. Also tried different aspect ratio settings.

First screenshot shows the local and remote pointers closely aligned in the top-right. Second screenshot shows local cursor near the bottom-left, yet remote cursor is in the middle of the screen.

I asked on the BliKVM Discord if this feature was available and it was explained to me that v4 currently doesn't support this feature.

Can relative mouse mode be added to the v4 device OS?

The password for the web interface appears to be stored in /etc/kvm.d/conf/admin.ini in plain text. This does not feel right.
Would expect it to be at least hashed with a salt using a sufficiently strong function.

Can you add a button "Ctrl+Alt+Del" to this toolbar? Now for this combination i have to open on-screen keyboard, press Ctrl+Alt on my keyboard and click "Del" with the mouse

As stated by the docs the feature is under development. Is there anything one can do to speed up this process? At the moment this is a major disadvantage compared to pikvm imho.

Hello,

Adding support for using HTTPS would be great.

I use NGINX as a reverse proxy and entrypoint of my house to the world, only available on port 443 for everything.

I tried to use it but then got this error when try to login:

Went ahead and opened the port 80 and was able to login but would would also need to open the port 8188 (would use unsecure WebSockets), I'm not willing to keep unsecure ports open, so my solution is just use ZeroTier and access through it on HTTP.

Thank you

connect to WIFI A and ping defined monitoring IP example 8.8.8.8, BLIKVM should keep the WIFI connection connected until defined quality parameters, example if we get 50% Packet loss, BLIKVM should disconnect SSID A and will connect to SSID B, and again will check quality of internet, Example if defined quality threshold is 50% , If 50% packets are lost from total sent packets BLIKVM should connect to next SSID C . We should be able to define 2 SSID or 10 SSID in the config file
The purpose of the above requirement is to keep the BLIKVM always online, If any further questions please send a message

Hello,

I recently acquired a cm4 pcie blicube blikvm and successfully installed blikvm on the eMMC of the cm4. Additionally, I inserted an SD card into the device to increase the available storage capacity.

Following the instructions provided in the expanding the file system guide, I ran the script to expand the file system. However, I noticed that the expansion only occurred on the eMMC and not on the inserted SD card.

I would like to request assistance in expanding the partition on both the eMMC and the available SD card. Could you please guide me on how to achieve this? Thank you!

Current version (based on the UI):

Version: 2.7.1
Build: 2023-02-26 12:29:31

The UI reports that an update is available and fair enough, when I look at the github releases I see that indeed there is a newer version. The update however appears to be hanging or not doing anything from the UI perspective so I established an SSH connection to the unit and ran:

rw
sudo -i
python3 /opt/bin/blikvm/script/update.py

which yields the following error:

Is this a bug with how the latest version is packaged or are we missing a file?

For the python oled script to start you have to install pip and pip3 install adafruit-circuitpython-ssd1306

oled使用久了会烧屏，最好增加oled关闭开关，同时为了避免用户忘记ip，关闭逻辑最好改为每次机器上电屏幕显示一定时常，显示完才判断开关状态，如果为关闭则不显示，为开则继续显示。
这样要是用户忘记IP信息至少通过简单重新上电再次获取信息，而无需重刷系统或者登陆路由器查看。

Hi Team,

I just recently found from the log, that the FAN speed is set multiple times within just a second.
Maybe that could be changed, so maybe just every 5min or 10min the temperature is checked and the FAN speed is adjusted.
I wouldn't think that this would be a risk for the CPU. But it would probably increase the FAN's lifetime.

Or I think maybe the temperature is checked every minute and if the CPU temp raises like 6 or 7 Celsius(as there is always some small mismatch of like 1Celsius when reading it 2 times one after the other) then adjust the FAN speed

Example from my log:
