Description Colin Guthrie 2008-01-14 02:10:18 UTC

Thanks to this commit: http://gitweb.freedesktop.org/?p=hal-info.git;a=commitdiff;h=b7e3b98992f0054d40e1f73c722d4710d650955b

I am no longer able to resume from a suspend.

I use a Dell Inspiron 6400 Core 2 Duo on Mandriva Cooker x86_64. With the latest hal-info I am no longer able to resume from a suspend.

In the past I had to apply a patch as noted in this Mandriva bug: http://qa.mandriva.com/show_bug.cgi?id=29448. That patch no longer applies due to this change but it is a simple matter of removing the vbe_state_restore quirk for this model (or combining it with the Dell Inspiron 640m, XPS M1210 definition). I have not done extensive tests of what the dpms_on quirk does - in my original patch I only applied the vbe_post quirk.

My system is using a framebuffer console and is running X with Compiz (although that last point shouldn't really matter). When I restore, the display shows text mode for a while before switching to X. With vbestate_restore, my screen stays completely blank.

Please let me know if you need any more testing. I will mail Casey Goodlett as he originally submitted the patch used in the above commit and I've CC'ed Danny Kukawka in this bug as he committed it :) (Casey's mail was not found in bugzilla, hence why I'll have to do that outside of bz).

After an upgrade to X, I also changed vbestate_restore to vbemode_restore.  Does this help?

Yes changing s/vbestate/vbemode/ makes things work OK for me.

Can you test your system with only the vbe_post quirk defined (remember to restart haldeamon - kept forgetting). For me this is the only quirk needed, but if your system likes the dpms and vbemode ones then I guess that's the ones to go for.

Using only vbe_post works for me too.

Great. Thanks for confirming.

Can this be applied to hal-info before next release please?

Just a friendly reminder to David that this still needs to be committed :)

Comment 6 Danny Kukawka 2008-03-14 05:50:07 UTC

I've commited something, that covers the machine to work only with vbe_post.
