Public bug reported:
Binary package hint: xorg
I had been having a Jaunty system freeze problem using the 173 NVIDIA
binary driver, and I could generally only recover with Alt-SysReq
REISUB. I couldn't access a console, because no consoles were
available. That was not a problem until perhaps a month or two ago, and
it seemed to get worse over time -- update problem? At its worst, it
was freezing multiple times per day.
Recently I switched back to the generic, open driver (actually, I tried
to switch to Nouveau, but it failed and tossed me back to the generic
driver, or so it said.
Now it freezes less often -- perhaps every day or two. When it does
freeze, I can access a virtual terminal. When running top, I've noticed
that memory used is very large -- on the order of 3009700K --
essentially the entire 3GB my 32-bit OS can address.
When I first observed that, Firefox 3.0.14 had ~8 zombie processes. I
killed them and freed up perhaps 300MB. I could restart X, but it froze
again, and this time I couldn't recover.
At another freez, I killed FF first and then saw that xorg had all the
memory (362m virt and 77m res, with 2770660K used overall. sudo kill
(pid of xorg) restarts X, but then it goes back to the same memory usage
immediately, even though I can get back into X. Ctrl-Alt-Backspace does the
same as kill (pid of xorg).
I've seen lots of complaints about Jaunty freezing, but I've not seen
anything about it freezing because xorg uses all available memory.
