thinkpad A21p display restore problem when opening top in X11
I just recently bought a Thinkpad A21p and it's a wonderful machine. I'm
running Debian unstable (Cid, I belive) and so far I have encountered only
one major problem: when I close the top for just a minute and then reopen
it, the display is almost always messed up.
This does _not_ happen when I suspend the machine. It only occurs when I
close the top for maybe a few minutes: the bios shuts off the backlight
(as it should). When I come back and open the top, most of the time
either one of two things happens:
1) The display is messed up in one of a couple different ways. Either the
entire screen is shifted over by about half (so the edge of the screen is
right in the middle, and windows that would be in the middle wrap around
off the right hand side over to the left) or it is shifted up several rows
(and there is some junk at the bottom of the screen.) Input still works
and the mouse pointer, oddly enough, is positioned correctly (maybe not so
odd, since I expect it's managed by the hardware seperately.)
2) The backlight comes on, but the display simply stays entirely dark.
Hitting keys, moving the mouse etc doesn't make it come back like you
would expect. I haven't determined if it's actually accepting input or
not.
The current fix I have depends on whether I am on battery on AC power.
If I'm on AC power, alt-ctl-F1 to a console and back fixes the problem[1].
If I'm on battery, for some reason alt-ctl-F1 doesn't do anything. It is
completly ignored. So instead I have to put the system in powered-on
suspend (with fn-F4) and then wake it up again.
[1] Another, possibly related problem, is that it does not restore the
console video mode properly. I get a nice fireworks show of screen
garbage. Hitting alt-F7 to return to X works. Since I use X for nearly
everything this isn't a crucial problem, but it is very annoying.
I've tried "xset s off" to disable the default X screet blanking, but it
doesn't seem to affect anything (well, it may prevent problem (2) but not
problem (1), which occurs more frequently anyhow.)
While on the subject, I have also noticed what appears to be X
missing/dropping enter-exit messages when the pointer moves from window to
window. In other words, if I move the pointer around quickly, the focus
sometimes will not be assigned to the window that the pointer is actually
on.
Attached is my XF86Config-4.
Okay, software versions:
xserver-xfree86_4.1.0-2
gnome-* 1.4.0.3-4
sawfish-gnome_1.0-2
linux kernel 2.4.8 (compiled from source)
Has anyone else experienced this problem? I suspect it's a bug in X 4.1
since I haven't been able to find it mentioned anywhere. I would
appreciate any suggestions of things to try or or maybe a pointer of who
to send a bug report to.
Thanks!
