[Desktop-packages] [Bug 1853266] Re: Xorg/Xwayland segfaults in OsLookupColor() from funlockfile() from glamor_get_pixmap_texture() from glamor_create_gc()
>From the upstream bug report, the failure in OsLookupColor() is just a common point where the system falls over once it's run out of graphics memory. There could be a number of reasons why the memory got exhausted in the first place (e.g. video drivers leaking memory, misc. bugs in GL apps, ...) which would be the root cause of the problem. (Fwiw, I stumbled across this bug report because I also got a crash in /usr/lib/xorg/Xorg (OsLookupColor+0x13c), but this was with radeon_drv, unrelated to any GL errors. So, likely a different underlying bug than the OP, just that the crash looks similar.) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1853266 Title: Xorg/Xwayland segfaults in OsLookupColor() from funlockfile() from glamor_get_pixmap_texture() from glamor_create_gc() Status in X.Org X server: Fix Released Status in xorg-server package in Ubuntu: Confirmed Status in xorg-server package in Fedora: Won't Fix Bug description: Recently, my the xserver on my system has started randomly crashing due to a segmentation fault.
