I am new to Linux, so please be patient with me.
I installed Linux Mint Release: 11 (katya) Edition: Gnome 32-bit a couple weeks ago. Everything in Linux seemed spectacular, until maybe 3 days ago, when it started crashing. What happens is that the Linux session freezes-up and reverts back to the login screen. The frequency of the crash seems to have increased in the last 2 days. It appears to happen at random, but when it happens I am normally using Google Chrome or perhaps a few other applications (I don't know if it's one or more of these applications or something else is causing it, but the session just dies). The whole session just freezes-up out of the blue (the GUI disappears, and I see a black screen with technical information - which I didn't capture - but no error messages) and then after maybe 10 seconds, I see the login screen again. I am required to log-in but the previous session is completely lost (all applications are gone, as if I just shut-down the computer or rebooted).
Please feel free to ask me any questions as I really love Linux Mint but this problem seems to be happening much more frequently now and I sincerely want to resolve it.
I have included a "lspci" below.
Thanks and regards,
