X Error BadRequest if in VNC server about maim

[naelstrof]

I can't replicate the issue: http://farmpolice.com/content/videos/f1506a11.webm

Can you give me more hints?

Does setting --mask=off help?

Oh I understand what it's doing now. My primary display :0 is actually 2560x1024, and it would be black since the machine is idle.

When I specify --xdisplay=:1 I get this:

$ maim --xdisplay=:1
X Error of failed request:  BadRequest (invalid request code or no such operation)
  Major opcode of failed request:  149 (RANDR)
  Minor opcode of failed request:  25 (RRGetScreenResourcesCurrent)
  Serial number of failed request:  9
  Current serial number in output stream:  9

And, I get that error regardless of whether I set --mask=off or include a filename.

Sorry that you had to open this huge can of worms, when I started to write maim a year ago I didn't even know more than one x screen could exist, but left in --xdisplay as a token measure.

This particular error is caused by maim trying to find the physical monitor sizes and locations using xrandr, but for whatever reason they don't exist in your virtual environment. (or xrandr simply isn't supported).

I'll try to figure out what's wrong.

If you mind helping me debug, I've pushed a commit which should get you past the X error: 04dcaae

I still need to set up reading the display from env vars and such, but it's really late and I should get some sleep.

I don't mind at all. slop and maim are great programs, I'd like to help out so I and others can be able to use them in more places :)

It segfaults now. gdb log: http://nylen.tv/maim/maim-gdb-01.txt

I'm not very familiar with debugging C/C++ code, let me know what I need to do next.

[naelstrof]

This should fix that: 5427e94

Okay, you are going to hate me :) your fix for grabbing the cursor worked, but:

now I get a blank screen: http://nylen.tv/maim/[email protected]
when I should get this: http://nylen.tv/maim/scrot-match-5247e9.png
but it works fine with --mask=off: http://nylen.tv/maim/maim@5247e9-mask=off.png

[naelstrof]

Haha no I love it that I have someone to help me flush out the --xdisplay functionality and error robustness.

510575a Should fix this.

You're on a bug killing spree! Works perfectly now.
