Hello guys, please help.
I'm having this odd issue with the new 3.2.38 kernel. I'm using Slackware 14.0 (64 bit) on Asus K53SD. So far, I've been regularly upgrading 3.2.x kernel without any problems, but this time GUI doesn't work as it should and I don't have a clue why.
After KDE starts it works for only a couple of seconds (20-30), then entire system freezes and nothing can be done except for a hard reset. If I don't log into a KDE session and switch to tty1-6 instead, everything works just fine. What troubles me most is that I made no changes to a kernel config, I'm still using the original generic config shipped with Slacware 14.0.
Since it only happens with GUI I expect, of course, a bug in a graphics driver. My notebook has nVidia Optimus, I have nouveau blacklisted, latest original nVidia drivers installed (have been using them with 3.2.37, working fine), but I'm not using bumblebee. If I'm not mistaken, KDE should be using an Intel graphics driver (included in kernel source).
This is a lspci output, if it helps:

Unless it's a bug, what else can be wrong? Does any one else have this issue?
Btw, I also have Slack14 on another notebook - Acer eMachines (HD Radeon) and everything works smoothly there with 3.2.38 so I guess it is related to the specific Intel chipset or the Optimus thing.
Thanks so much for any info.
