X errors and crashes

[Dodger73]

So, ever since my upgrade to Feisty, many applications won't start (for example Firefox, or Synaptic), and any kind of OpenGL (Beryl, screen savers) will actually cause a crash and re-start of the X server. Here's what I'm getting as an error from firefox, for example - the error is the same with any application that won't start:


QPainter::begin: Cannot paint null pixmap
QPainter::setPen: Will be reset by begin()
QPainter::setFont: Will be reset by begin()
QPainter::end: Missing begin() or begin() failed
The program 'firefox-bin' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadValue (integer parameter out of range for operation)'.
(Details: serial 471 error_code 2 request_code 53 minor_code 0)
(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.)


I'm running a GeForce6600 with the latest drivers from the NVIDIA website.
Any hints would be greatly appreciated!

[EDIT] after installing the 9746 drivers instead of 9755, OpenGL doesn't crash the X server anymore. However, the X error pasted above is still there.

Re: X errors and crashes

Update: I have a feeling that this is somehow related to the GTK libraries, or the ones that pipe GTK through QT, since firefox, synaptic and beryl-manager (which now produces said X error instead of crashing X) are all GTK applications. I've tried reinstalling all GTK and QT libs, to no avail. Any takers?

Re: X errors and crashes

Another update: uninstalling gtk-qt-engine fixes the problem (of course then GTK apps look pretty bad, but at least they don't crash ). So, there seems to be a bug in gtk-qt-engine...

Re: X errors and crashes

I just received the same error, and fixed it following the above instructions (I somewhat recently upgraded from Feisty to Gutsy). The error Konsole gave me was as follows:

~$ firefox
QPainter::begin: Cannot paint null pixmap
QPainter::setPen: Will be reset by begin()
QPainter::setFont: Will be reset by begin()
QPainter::end: Missing begin() or begin() failed
The program 'firefox-bin' received an X Window System error.

The error was 'BadValue (integer parameter out of range for operation)'.

Re: X errors and crashes

Update: The error seems to be with the KDE style -> GTK apps, because if I choose another style that is GTK specific, such as Clearlooks, my GTK apps work fine. However, if I choose the Use my KDE style in GTK applications option, or select the QT (not QTCurve) style, my GTK apps won't open and give me the error code listed above.
