I have sampled about 5 Linux distros, and have found Kubuntu to be my favorite as it is the most stable, and works the best with my Vaio. However, I have been unable to get suspend to disk and suspend to ram to work. I have searched through threads everywhere and have modified a few config files attempting to resolve the issue to no avail.

When I suspend to either, upon waking, the screen will not turn on and the computer remains silent but the LEDs will work. However, in OpenSuSe and Fedora 12, suspend works fine. What I want to know is if there is a way I can view the settings on one of those distros, and apply it to Kubuntu somehow. I understand the files are different, but perhaps it has something to do with the kernel?

Any input or advice would be great! Thanks!

Which type of video card?

I am using an ATI Mobility Radeon 3400. I am using the proprietary driver, which could be the cause of it. I know in Fedora there is an open source driver which will allow for 3d rendering, but the one in Kubuntu/Ubuntu will not. Could this be the cause?

While that could be the problem, I am not sure it explains why my computer fans will turn on, but nothing else. I almost feel like it is a kernel issue, but that is far beyond my comprehension.

In Fedora 12 you were using the open source driver. That is likely the case too with opensuse, imho, so you will not simply be able to copy the configuration settings over.

The proprietary drivers are often problematic when it comes to suspend and resume. Getting it to work depends on the right combination of video card, drivers, bios, birthday, phase of the moon, and week the computer was manufactured. As for the it being a kernel issue. It's certainly possible. Even likely. But bear in mind that the proprietary drivers create and use a kernel module, which is likely the cause of the problem.

If you wanted, you could try to use the open source drivers via the xorg-edgers ppa and an updated kernel.

Thanks for your input Adam. So far as I know, the graphics card chosen by default for my video card is the open source one, but it is incapable of rendering 3d and wont allow for any desktop effects. Call me picky, but one of the reasons I love Linux so much is how customizable it is and how much more fun it is to use.

As a test, I removed the proprietary driver and rebooted. I then attempted to suspend the computer with the same results. The LED lights come on, but it seems like the computer will not wake up. I really am curious as to what exactly it is that is not working. There has to be some config file in which something that needs to be set to true or false is set the other way. Or, perhaps, something needs to be reminded to restart.

Which is why I mentioned the driver in the xorg-edgers PPA. It is capable of 3D acceleration.

Now, then, it does seem much less like to be related to the proprietary driver :-) Unfortunately, I have no idea what might be causing that problem.

Adam

Oh, I had no idea there was another driver available. I knew Fedora had one available, which was a little buggy. I will go check that one out. If not to help with the suspend issue, at least to avoid using proprietary drivers.

Thanks Adam.

Here's a quick guide I found on the ubuntu forums that pretty much covers it. It's from October of last year, but is more or less accurate. Obviously if you can find a newer kernel in the kernel-ppa than 2.6.32-rc5 (which I'm sure you can) I would go with the newer kernel. The xorg-edgers ppa is updated regularly. It is essentially the same driver that F12 uses, but developed even further for the past 6 months :-)

Adam

Can you post the link to those forums?

Yes, that would probably help :-) Sorry.

Well, I finally figured out how to upgrade the kernel and get the open source drivers. I have to thank you Adam, because so far the graphics are MUCH smoother and faster! The suspend still doesn't work, but that will get figured out in due time.

Thanks man!
