I've only seen this with xscreensaver, but another person another distro says in Quake IV also[1]. for some x-screensavers (eg mirrorblob, starwars) this message always flashes in yellow, over the screensaver: fglX11AllocateManagedSurface: __FGLTexMgrAllocMem failed!! sometimes 4 in a row, sometimes 20 in a row. The result is a "stutter" or otherwise bad performance in 3d. gentoo-user discussions led me to check /dev/shm: $ ls -al /dev/shm/ total 16 drwxrwxrwt 2 root root 60 2007-07-18 08:33 . drwxr-xr-x 15 root root 14180 2007-07-19 08:32 .. -rw-rw-rw- 1 iain users 1048576 2007-07-18 08:33 ATISHM00 and from /etc/fstab: tmpfs /dev/shm tmpfs defaults 0 0 I tried purging /dev/shm, unmounted and remounted, but no change.

Bugs reproducible on Ubuntu are apparently not Gentoo specific, you need to complain to ATI. (In reply to comment #0) > I tried purging /dev/shm, unmounted and remounted, but no change. This is a *very* bad idea.
OK, the "bug" exists with all these versions: 8.36.5 8.37.6 8.39.4 8.40.4 but not with 8.34.8. I recompiled and rebooted in-between each one, then ran the mirrorblob screensaver to test. I am re-opening this so that 8.34.8 doesn't get removed from portage, and so that other versions can be marked unstable if seen fit. If this isn't the right way to do it, just let me know :)
Yeah, thanks but there's still nothing we could fix here. To get it fixed in latest versions, you still need to complain upstream and not here. Sorry.
