Bug 241902 – XChat uses shm pixmap hardcoded which is an optional feature.

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Christian Birchinger (RETIRED) 2008-10-14 09:18:50 UTC]

x11-drivers/xf86-video-i810 2.4.2 does not offer shm pixmap support when EXA is being used. X-Chat calls this feature hardcoded and crashes unless EXA is disabled ("NoAccel", "EXANoComposite" etc.)

Error:
The program 'xchat' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadImplementation (server does not implement operation)'.
  (Details: serial 313 error_code 17 request_code 146 minor_code 5)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

The following patch should fix this issue.

Reproducible: Always

This patch should make shm pixmaps optional in X-Chat

xchat works fine for me with xf86-video-i810 and EXA acceleration.

XChat-Gnome had the same problem:

Ok, it happens to me as well after configuration changing - for reproduction you need to have transparent background enabled in xchat

[Comment 5 Bernard Cafarelli 2008-11-18 12:14:31 UTC]

Also happens with nvidia (binary driver) when transparent background is enabled:

Suggested patch works fine
