suspend to ram again.... :(

English Hardware

Sorry, i know this might be very annoying, but I’ll try to describe my problem as more detailed as I can. After suspending the computer to RAM using the button in the Application Launcher, my laptop goes to sleep properly, but on the resume it freezes. I get a black screen and no buttons seem to work at all, even the Capslock indicator does not light up.

Here is my configuration:

Opensuse 11.1 i586
4.1.3 (KDE 4.1.3) “release 4.10.4”
Intel Core 2 Duo CPU T7500 @ 2.20GHz
3GB RAM
ATI Radeon HD 2600.

I installed the driver for the video card manually using the method described here: How To: ATI Drivers OpenSUSE 11.1 - Ubuntu Forums. Since OpenGL seems to be working fine, I suppouse that the driver installed correctly.

I read the “Suspend to RAM article”, and tried “vga = 0” with “s2ram -f -p -m”/“s2ram -f -p -s”. The computer went to sleep properly and actually did resume, but started acting really weird, e.g. I got a really messed up mouse pointer looking like a white box, ctrl + alt + backspace didn’t work, weird images appeared while restarting, etc. Turning apic off didn’t work at all. Does anyone here has an idea of what the problem could be? Any help will be highly appreciated.

Don’t think this will solve your problem, but might help narrow it down.

I noticed a similar issue on my laptop whenever I was using the fglrx (ATI) driver. If I removed it and went back to the opensource radeon driver, suspend worked just fine. I have an older laptop with an ATI X1300 card, so you may have to use the radeonhd driver.

For me, I was unable to find a solution that worked with fglrx, but I would rather have the capability to suspend than to have the fancy graphics. The only thing I have noticed that the fglrx drivers have over the radeon is the ability to run the desktop effects (compiz, etc…).

If you find that it is the video card driver that is the problem, and you find a solution, let me know as I would like this working as well.

hmmm
i have actually found the solution to this problem. In Power Management, I left the “Lock screen on resume” option blank, and it really did work. I’m getting perfect suspension and resuming in just a few seconds. So, now I really don’t know if it is somehow connected to the fglrx driver or not. elserj, try this thing out, it might work for you too.
