Public bug reported:
Binary package hint: xorg
This is possibly not the same as bug 457695 as it is on different
graphics hardware, although there are similarities. This is Acer Aspire
7520 with Nvidia graphics and Nvidia driver.
First noticed in Kubuntu 9.10, but parallel installation of Ubuntu on
same machine has exactly the same problems, so it is probably not a KDE4
bug.
First indication is that the shell, in a GUI window (konsole or gnome
terminal) just dies. It stops responding to keystrokes, but as the GUI
is still working, it can be closed. It will then not restart. It dies if
a running non-GUI program is generating output, or when manual keyboard
input is occurring, and may be a few seconds to (rarely) an hour or more
after startup.
On attempting to bring up a virtual TTY to investigate, it was found
that keystrokes were having no effect except in any open GUI window such
as a text editor, where all works normally. After tghe shell dies, keys
are not seen outside the GUI window so can't start any of the virtual
consoles by <CTRL><ALT>F1 etc.
On fresh boot, again in Gnome or KDE, before shell has died,
<CTRL><ALT>F1 etc bring up black screen, with no cursor, no respones to
keyboard, etc. Backlight is still on. <CTRL><ALT>F7 returns to GUI
correctly. After shell has died, <CTRL><ALT>F1 etc do nothing, so there
is no way of getting a dmesg etc after the event. Maybe I will be able
to set up SSH to have a look, but not yet, as I need another machine. At
the moment the only thing to do is to reboot via the GUI, logging out or
restarting X does not seem to get the shell working again.
I think but can't yet prove that there may be 2 distinct bugs here, one
because the virtual TTYs are always dysfunctional, and the other, the
shell dying, but it could all be the one bug.
The screen resolution is its native 1440*900, if that is relevant.
This problem was not seen in 9.04, 8.10 or 8.04 on this hardware. The OS
is currently unusable for serious work because I need the shell.
Suggestions for further tests will be gratefully received.
