suspend2 and fglrx

[skrionius]

Any tipps and trick how to make FGLRX work together with Suspend2?
It freezes with 8.18.8. (kernel 2.6.14) Is there a working version? Or something which makes it work?

vbetools workaround does not work. It says it cannot save the state because it cannot get the data needed. maybe fglrx is in the way?

Anyone who got it working?

[skrionius]

So it seems no one uses suspend2 with fglrx. A sorry state. It can save some time when you dont have to boot your machine from the bottom! With XOrg driver it works well and restores whole system from swap partition. Like in windows the hibernation thingy. Cool!

Hi,

I got fglrx nearly working with suspend2.
My Samsung P35 resumes when using vbetool, but my screen under X (KDE and GNOME) is garbled. The screen isn't "redrawn" so that when e.g. scrolling in Firefox I only see the top of the page all the time.

Did you use vbetool under the console? That's needed. How does your hibernate script look like?

I didnt edit anything in hibernate script!
You edited it in some way to run vbetool in console mode?
Can you please post about how you did it, or an example script/config?

Thanks!

[Whoopie]

Sorry, but my laptop is under repair. It comes back next week.

But what I have in mind is:

hibernate.conf:

### vbetool
EnableVbetool yes
# RestoreVbeStateFrom /var/lib/vbetool/vbestate
VbetoolPost yes
# RestoreVCSAData yes

### xhacks
SwitchToTextMode yes
# UseDummyXServer yes


And I changed in /usr/share/hibernate/scriptlets.d/vbetool:

if [ -z "$VBETOOL_HOOKED" ] ; then
AddSuspendHook 02 VbetoolSaveState <-- before 97
AddResumeHook 97 VbetoolRestoreState
VBETOOL_HOOKED=1
fi

It's nearly at the end of the file.

Check out 8.19.10 it has some added initial support for suspend and resume, haven't been able to test it yet.

[skrionius]

Good news, i hope it is for suspend2 not only old software suspend! I am downloading it right now and will test in a couple if minutes.

Just built it with my unofficial x86 ebuild for 8.19.10. (Its ebuild 8.18.8 without revision, it didnt compile for me..) You can do it yourself easily.


Test starts now ...

[skrionius]

Now, driver works well. fgl_glxgears is faster when i use -fbo option. But suspend is worse than before! Now suspend2 fails to suspend my machine, and it hangs when trying to recover.

With older driver suspension happened. Now it is unable to do it. No matter if I use vbetool or not.

Also if possibly try to use a more recent kernel. These will work better.

Using kernel 2.6.14 and no vbetool, hibernate of suspend2 is unable to suspend! maybe it needs some fine tuning yet on side of hibernate script?

PS: After some experimentation I found that if fglrx is loaded, suspending freezes in the end. I think it must be related to fglrx module.

For now til its fixed, or somebody gives me an idea, i will use hibernation with save session, killing X and blacklisting fglrx driver. At least it I gain a lot of boot time, X starts from cached state and my apps will be restored by gnome next time I login.
My brute script:

#!/bin/sh
echo "SAVING GNOME SESSION" 
gnome-session-save 
sleep 2
echo "KILLING X" 
killall X 
sleep 1 
killall -9 X 
killall gdm 
sleep 1 
killall -9 gdm

And I appended fglrx to blacklist.
Also added
OnResume 20 xdm
to hibernation config...

Please anyone report successful hibernation with suspend2 kernel and new driver! Thanx

I know suspend2 is all spiffy and cool and stuff, but can you just revert to original suspend?

Back in my gentoo days I only used suspend2 because I managed to get a funky workaround to work with the ati driver that suspend wouldn't work with.

Now I'm using ubuntu and the suspend that is enabled by their kernel seemingly is using plain ol' software suspend and working like a charm.

[skrionius]

Ok, I will try to revert! And does old sw susp work well with fglrx?

I have tried suspending to disk with old suspend, and it kernel oopsed...dont know why.. I think I will stick to my X killer suspend2 script for now

I recompiled my kernel with pure suspend support without suspend2 and the kernel oops went away, but..

Suspend goes right to harddisk, shut down happens, and all seems to be resuming, but X is messed up and after some seconds of use it totally hangs... (no vbetool or anything)

I have R9600XT, using kernel 2.6.14.

i managed to use internal and external AGPGART with my mobo... but still it freezes with suspend.

Hi!

My computer is a AMD Athlon(tm) XP 2600+, nForce 2,
1Go RAM, Radeon 9200SE

Just one success for suspending my PC using software suspend 2.2-rc11
I'm using FC4 kernel from http://mhensler.de/swsusp/
and livna ATI RPM!

And It Work !!! Good job ATI & Software suspend 2 team !
We need sofware suspend 2.2-rc10 (or more) to make it work.
With version < 2.2rc10, Software Suspend freeze at "atomic count"

Good job!

EDIT: well, after severals (>3) suspend crash my computer,
but maybe it's not an fglrx issue
- 3D acceleration is still present after suspend! (Good!)
- XV doesn't work anymore after suspend (bad...) => black screen
EDIT2: I found the process who give me errors when suspend/resume
It's "wpa_supplicant" (doaemon for WPA on my Wifi card (under ndiswrapper)
I just have to kill this process just after network down,
just add in conf file: /etc/hibernate/hibernate.conf
"OnSuspend 61 /usr/bin/killall wpa_supplicant"
then, I don't have crash anymore!
And for XV, I just change my prefs in mplayer from "xv" to "gl"

[skrionius]

Tried 2.2-rc11 and WORKS PERFECTLY!!! Yes it is!! recompiled kernel, plus driver, and it suspend to disk and resumes...

Anyone using Suspend2 and fglrx willing to write up a Wiki page?

I started a wiki page at http://wiki.cchtml.com/index.php/Suspend2 so please edit it into something useful

[Whoopie]

Hi,

I also tried fglrx 8.19.10 and my Samsung P35 suspends and resumes without freeze.
But nevertheless, my screen under X (KDE and GNOME) is garbled. The screen isn't "redrawn" so that when e.g. scrolling in Firefox I only see the top of the page all the time.
That's the same problem as with the older drivers before.

Any ideas?
I'm using Ubuntu Breezy with kernel 2.6.14.2 and suspend2-2.2-rc11.

Regards,
Whoopie

Okay, I throw up something initial. Maybe it should need some compatibility tables later... I am not a mage of wiki, but if I have time I will try to keep it updated.

In my pc suspend works but resume not! It hangs when it brings up the X Server.

When I first start my pc I get this in message log

Oops, its not so perfect!! I tried opengl thingies, and they are completly disabled upon resuming! ATI part of extension is gone totally. No opengl overlay and glxgears crashes!
Anyone experiencing the same?

EDIT: Sorry, something must be messed up! Maybe it is loggin in multiple times to X..i will experience some more...

BUT XV overlay is blank for me too, just like reproted by someone else!

EDIT2:
Another bug is that if I run Nested X (multiple logins to X, multiple screens), the first insance from which I suspend is working,but when switching to the second screen (Ctrl-Alt-F8) it hangs totally.

[Septor]

I think the "XV doesn't work after suspend/resume" is a known bug.

Yes it is. But partly it does work! mplayer is not but tvtime is working. So its not that simple for me at least XV is not totally ruined..

EDIT: but now it is totally! even tvtime isnt working.

It shows tv for a very short time milisecond maybe, and then goes black.

One short question:

Should I disable PREEMPT in the kernel or not?

Doesn't matter. I have it enabled though, if that's any help. If you get PREEMPT kernel oopses, then try turning it off. If not, should be okay.

[skrionius]

I am experiencing problems with resuming again... :| It is ocassional, and I couldnt find out what is the cause! X screen remains blank, I am on console and can press numlock/capslock, so its alive...but when pressing alt-f7 to go to X it freezes... It happens rarely, especially if I dont use the computer for a long period. I am clueless why it does happen!

[Whoopie]

Hi,

I found following messages in dmesg after resume:

[fglrx:drm_free] *ERROR* [buflist] Attempt to free NULL pointer

Could this be the reason for my garbled screen under X after resume?

[skrionius]

After a whole day of hacking around...jesus..i found that the simpliest thing was in the way..i had occasional hangs. And all caused by a proxy service running! (Used tinyproxy and ziproxy.) Now it works very well again without them!

[skrionius]

After some time using suspend2 and fglrx with multiple suspend/resume I
observed some weird thing. After some relogins/resumes with another user
in GDM, DRI of fglrx went away, opengl disappeared. Loggin in again made
it appear again, but then after hibernate -- resuming hanged my
machine... so still things to be improved with fglrx a/o suspend2.
