Binary package hint: xserver-xorg-video-nouveau
I got back to my machine in the morning to find that the display showed a
slightly corrupted opengl screensaver image with the following text at the top
of the screen:
gltext:../../nouveau/nouveau_pushbuf.c:273: nouveau_pushbuf_flush: Assertion
`!nouveau_pushbuf_space(chan,min)' failed.
xscreensaver: 19:48:14: 0: child pid 5290 (gltext) terminated with signal 6.
The keyboard is dead in a 'scroll lock/numlock don't change the LEDs' sort of
way.
I can still ssh into the machine and X is still running (using 66% CPU) along
with all my other apps and processes.
xscreensaver master process is still running too. It does not respond to
DISPLAY=:0 xscreensaver-command -deactivate
(or -version)
stracing the command shows:(snipping a load of startup file checking):
...
socket(PF_FILE, SOCK_STREAM|SOCK_CLOEXEC, 0) = 3
connect(3, {sa_family=AF_FILE, path=@"/tmp/.X11-unix/X0"}, 20) = 0
getpeername(3, {sa_family=AF_FILE, path=@"/tmp/.X11-unix/X0"}, [20]) = 0
uname({sys="Linux", node="e102475-lin", ...}) = 0
access("/home/wookey/.Xauthority", R_OK) = 0
open("/home/wookey/.Xauthority", O_RDONLY) = 4
fstat(4, {st_mode=S_IFREG|0600, st_size=0, ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0x7f37c42e7000
read(4, "", 4096) = 0
close(4) = 0
munmap(0x7f37c42e7000, 4096) = 0
fcntl(3, F_GETFL) = 0x2 (flags O_RDWR)
fcntl(3, F_SETFL, O_RDWR|O_NONBLOCK) = 0
fcntl(3, F_SETFD, FD_CLOEXEC) = 0
poll([{fd=3, events=POLLIN|POLLOUT}], 1, -1) = 1 ([{fd=3, revents=POLLOUT}])
writev(3, [{"l\0\v\0\0\0\0\0\0\0\0\0", 12}, {"", 0}], 2) = 12
read(3, 0x1440590, 8) = -1 EAGAIN (Resource temporarily
unavailable)
poll([{fd=3, events=POLLIN}], 1, -1 <unfinished ...>
Which seems to shwo that the X socket simply isn't responding, so the
server is dead to useful activity.
hupping the X process doesn't help. restarting gdm (and thus X) makes
the display fill with random stuff (lots of little tiles of X stuff) but
the keyboard is still dead. Only rebooting the machine gets you back to
a useful state.
This appears to be the same bug as
https://bugs.launchpad.net/ubuntu/+source/extremetuxracer/+bug/612971
provoked by a different app, and extremely similar to the older (Karmic)
