So I'm not necessarily a noob to linux, but I am a noob to using the forums process to solve my problem. This is the first time that I've run into something that someone else didn't seem to already have solved. Thus, I have no idea what kind of information I need to draw from my machine or where to get it so that someone can look and see what's going on with my system. Here is the issue. Installed Kubuntu 12.10 about a month ago. Since that time, the machine runs fine in general, but if it goes to screensaver mode or if I lock it and walk away for more than 1 hour, I have to power cycle my machine. I can't get the machine to come back and I can't get into the text-only mode. I can recreate the freeze by locking the machine and walking away, but the timeline isn't always consistent. At times, it'll be fine for 5 hours, then freeze. Sometimes it'll only take 15 minutes. What information do you need me to put up so you can help me find the root of this problem?

Board: ASUSTek M78N3-EM
CPU: AMD 7850 Dual Core 1400 MHz
GPU: Radeon HD 5450
RAM: 8GB DDR2
Swap Partition is 9.5GB
I have a / and /home setup so that I can try out different flavors without losing my docs. My / partition is 27.9 GB and only 6.9 GB is used.Comment

Which kernel? You can check with
Code:uname -a

No. I disabled the screensaver thinking it to be the root cause of the problem. Same result. Now locking the computer goes to a blank screen. I can still log back in, but if I leave it for a bit, it freezes up.Comment

@jastring: how would you rate your skills manually downloading and installing .deb packages? I'd like for you to try a newer kernel, and I'd like to have an understanding of how much detail to include in my instructions.Comment

Nope. The Kernel PPA stoped publishing after Lucid. The Pre-proposed Kernel PPA still publishes, but only updates within the series currently used by a release.
To obtain newer kernels, you have to download the individual .deb files for linux-image-version_arch, linux-image-extra-version_arch, linux-headers-version_all, and linux-headers-version_arch. After you download the four files, you install them via:
Also, it's OK to move forward a release. I wanted 3.8 on my Quantal box, not 3.7. Right now, I'm running the 3.8.3 Raring build on my Quantal laptop. Works great. nVidia blob, VirtualBox, and VMware Player are happy as clams.Code:dpkg -i linux*deb

Remember that the kernel image is now split into two files, so don't forget the -extra- one.Comment

As a nice bonus, Intel rc6 power saving is very functional under 3.8.x and works great.Originally posted by vinnywright View PostLOL ,,,,,,,agreed
