I did a system upgrade yesterday (Friday 8 Feb). The following (possibly relevant) packages were upgraded: mesa libgl xorg-server xf86-video-intel firefox After I did the upgrade, I shut down my box. When I restarted tonight, Firefox kept crashing, and giving this error message: The program 'gecko' received an X Window System error. This probably reflects a bug in the program. The error was 'BadAlloc (insufficient resources for operation)'. (Details: serial 1625746 error_code 11 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.) Because it kept crashing, I tried Opera (which I use for testing and as a backup). It started, but returned this message (which I had never seen before): opera: X Shared memory extension is not available. ZPixmap not supported Because I am getting unusual errors in both browsers (and the errors are related), I think this is at a lower level. My system is a Core 2 Duo with 2GB RAM and 400MB swap (which is not used at the time Firefox crashes). Has anyone else experienced any of these problems? Does anyone have any suggestions? Scott
