Description Kenn Humborg 1999-12-06 01:12:59 UTC
Boot into text mode.  Log in as normal user (non-root).
Start an X session with startx.  Gnome desktop appears
as normal.  Hit Ctrl-Alt-F1 to switch back to text
console.  No problem here.  The monitor does its
re-syncing thing and clicks a relay as it adjusts to
the new video signal.  Hit Alt-F7 to switch back to X.
I get a blank screen.  The monitor doesn't resync,
suggesting that the X server hasn't re-programmed the
video card for graphics mode.

At this point, I have to reset the machine.  Ctrl-Alt-Del
works, both no other keyboard stuff works.  Caps-lock
doesn't toggle the LED.  Typing blind doesn't do anything
(such as echo XXX > /var/tmp/test ), even though an xterm
definitely would have focus on the X desktop.

Video card is Imagine I128.  XFree RPMs are 3.3.5-1.5.x.
I'm running xfs.  My gnome-core is 1.0.4-13rh and gnome-libs
is 1.0.8-2rh.  I can provide version of other gnome packages
if you want.

Interestingly, this doesn't happen if I start X by justing
running the X-server directly.  Of course, I only get the
'dots' initial X screen, but switching over and back to
text mode works fine.

Ditto when running xdm...
Autostart xdm for remote users, Ctrl-Alt-F2 for server console, and if you
attempt to switch back, everything locks up.
Ctrl-Alt-Del will not function, I'm forced to telnet in, and force shutdown to
regain the server console.

I don't seem to have an issue if I complete a xdm logon at the server console.

imagine 128 cards had problems with XFree86 3.3.5, but they have been fixed in
3.3.6 (next release).
