Hello, today my system has started exhibiting a weird behavior. When KDE starts, I get stuck in a blank screen. Sometimes, KDE starts and shows the logon page, but then it gets stuck during logon: the disk icon is completely loaded, but the others are still blurred.
I can dual-boot into windows on the same machine, and it also has problems. Can you help me diagnose what the problem is? I have remote access to the machine, and I can even start X remotely, although it's sluggish.
I have an nVidia 9600 card, which had been working just fine until today. I have tried updating to the last nVidia drivers from the PPA, but it didn't help.
Thanks in advance,
