resume still work well when the laptop suspend by closing the lid.

here is a log during a 'bad' resume : http://pastebin.fr/25770

does anybody have an idea what's going wrong ? is the same command invoked when going to suspend by closing the lid and by idling ? -- Mathieu R. http://400iso.net/

Hi Mathieu, what's your video card? $ lspci | grep -i vga will do it. Also: 1. do you have installed acpi, laptop-mode-tools or pm-utils? 2. what does happen if you suspend your system using the pm-suspend tool? A $ man pm-suspend will give you useful data about the quirks flags you can use.

I get the same problem after resume under Xfce, unless the screen is locked. The mouse cursor seems to see windows, as its shape changes when I move it, but I don't.

I have to go to another TTY, restart gdm, and log in.

I got to a text console, set $DISPLAY and launched xkill, in case the black background have been a window of some software. No effect (I probably killed a random application). I then sent the lock command to the screen saver. It took over the screen, I unlocked it, and I get back my screen with visible windows. So adding a hook to lock screen to /usr/lib/systemd/system-sleep and /etc/pm/sleep.d avoids the problem for me most of the time, even if that doesn't really solve it. I don't know whether Gnome screen saver will do the same for you, neither the command to activate it, but it's worth to try. On 2012-11-04 05:05, Martín Cigorraga wrote:

I will answer for me: Advanced Micro Devices [AMD] nee ATI Radeon RV250 [Mobility FireGL 9000] (rev 01) (It's quite an old beast. On a more recent laptop with more or less the same configuration for the system, I don't have the same problem.)

Also: 1. do you have installed acpi, laptop-mode-tools or pm-utils?

All of them.

2. what does happen if you suspend your system using the pm-suspend tool?

I works as described. On the other hand, suspend from systemd doesn't even success to suspend this laptop. Only hibernate works (with the famous black screen when waking up).

A $ man pm-suspend will give you useful data about the quirks flags you can use.

Tried pm-suspend --quirk-radeon-off with no more success. -- Laurent Dudouet
