Intel 945GM: 2.6.25-rc3 report (with a possible regression)

Intel 945GM: 2.6.25-rc3 report (with a possible regression)

[Romano Giannetti]

Hi,

this mail is to give feedback about the 2.6.25-rc3 kernel, on an Ubuntu
7.10 system, running on a Toshiba Satellite U305. Video is a Intel
845GM, and I run 915resolution at start to make X happy with the correct
widescreen resolution. 

A lot of data is collected here (if more is needed, tell me):
http://www.dea.icai.upcomillas.es/romano/linux/info/

1) The minor regression is that I cannot have any more a correct
console. I tried a lot of combinations, but without a framebuffer,
console is garbled by ubuntu splash and/or X. With the .config copied in
the site above, I do not have console (a random pattern appears as I
switch consoles). With intelfb framebuffer, sometime it works, sometime
it doesn't work, and everytime break resume from STR. (I mean, the
laptop seems to resume, but the screen is blank).

I have a doubt about this: is it possible that some state is maintained
across reboots? Because sometime two reboots in a row led to different
results; for example, after following 
https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/147606

I had a nice console, but after the failed resume and a sysrq-b reboot,
no console again. 

2) LCD/CRT switch. It's the first time I tried it, so no idea if it ever
worked. Without a CRT connected, nothing happens pressing the key
combination (fn-F5), correctly. When I connected a overhead proyector
(CRT), pressed fn-F5, and the LCD went off and the CRT on (ok); after
that the LCD never came on again. pressing again fn-f5 two times lead to
a all-off, a third time made the CRT switch on, and again. The laptop is
working but the LCD stay black till the next reboot. (It is very similar
to what seems to happen after resume).

3) on the nice side of things, it seems that now echo mem
> /sys/power/state works (at least in X, I do not have a console to test
it...).

Thank you very much, 
		Romano

Are you sure that this is a kernel regression, not a xf86-video-i810 
regression?

(On Gentoo, switching from X to console works with xf86-video-i810-2.1.1 
but results in a black screen with xf86-video-i810-2.2.0.90.)

Yes, the X.Org developers are making major changes ATM and there have
definitely been regressions because of them.

Best way to find out is to check whether booting with an earlier kernel
solves the problem. If it does, it's most likely a kernel issue. If it
does not, it's most likely an X.Org issue.

This sounds like that could be a bug I filed recently and which was solved
in 2.2.1: http://bugs.freedesktop.org/show_bug.cgi?id=14481.

Indeed, 2.2.1 fixes this issue for me.

Yes, it seems the same. I will try as soon as I came around to a way to
do it. 

Could this account to the LCD/CRT switching problem to? This is the most
critical to me, since I can't use the laptop to give presentations. I
double checked if the key combination is managed in user space, but it
seems that it did not send ACPI events nor keypresses, so I suspect that
it is a kernel matter (or BIOS, maybe).

I'm afraid I can't help you there.

As I said before, the only way to make sure is to see if the problem gets 
solved if you boot the system with an older kernel version.

Well, in this case I do not think it ever worked, so it's not a
regression. But still would it be nice to solve it... thanks anyway!

Ah, OK. That wasn't clear to me.
If it's not a regression, tracing the problem will be much harder.

The best way to start is probably just to google to see if other people with 
the same laptop or video controller have the same issues (and maybe 
solutions). Look for installation reports for your laptop model for 
example.

> But still would it be nice to solve it... thanks anyway! 

I have had LCD/VRT switching issues with my laptop as well (a Toshiba 
Satellite A40). The Fn key did always work, but the output after switching 
would be garbled and I could not switch back. This was finally fixed about 
a year ago with the new Intel drivers and xrandr 1.2.

Your problem may be totally different though and could possibly be related 
to the function keys, or indeed to the BIOS.
Note that some laptops need special kernel modules or user space programs to 
be loaded for the Fn keys to be supported. Have you checked for that?

Good to see we're fixing things for some people at least (re: Stephan's 
message).

The 2.2.1 release may nor may not affect your LCD/CRT switching, but I know at 
least 2.6.25-rc3 has some ACPI key event reporting issues that may be fixed 
now (at least in the ACPI tree).
