[ltp] Power and graphics on T41p

[Cameron McCormack]

Hi everyone.

Well I've had my new T41p for a few days now and I'm trying to work out
some problems.

The first problem is with X.  I am using ATI's fglrx module.  If I am in
X and try to switch back to a console (which is using the framebuffer)
then the screen goes all garbled.  Occasionally I can type at the
garbled screen and "reset" will fix things.  Most of the time though the
machine will just hang and I have to hold down the power button to turn
it off.  How can I get it to behave properly?

My other problem is with power management.  I can't get ACPI to suspend
properly.  I do "echo 3 > /proc/acpi/sleep" and the screen goes garbled
and crashes.  With APM I have a bit more luck.  I can type "apm
--suspend" and it will go to sleep and pressing Fn will bring it back up
again.  I noticed one time that my USB mouse didn't recover properly
after this suspend/resume sequence, but other times it did.  Pressing
Fn+F4 also seems to work properly.  Is there any difference between
pressing Fn+F4 and typing "apm --suspend"?

Pressing Fn+F12 just results in a low pitched beep and no hibernation.
Does this mean the BIOS can't do it?  I guess I will investigate swsusp
and the other alternatives.

Trying to suspend while in X results in a corrupted display and then I
couldn't recover it.  I could Alt+SysRq+B to reboot, unlike the hang
when I switch to console mode from X as mentioned above.

If I boot with my USB mouse connected then I can't use the track pad or
track point.  If I boot without it connected, then connect it later, I
can use both.  Can I fix this?  I guess I should investigate the
synaptics driver at some point.

Well I think that's all for now.

Thanks,

Cameron
