I am getting a lot of lock-ups after screen is turned of by PowerSaver. When I come back to use laptop I get a frozen display. Only way to recover is to hit the power button and switch off which gives loads of hard drive errors on restart. Most of the time these errors are resolved automatically but sometime it asks and I have to guess the answers. So far it has restarted okay every-time.
LMDE Xfce 64bit, with all latest available updates.
Intel Core 2 Duo SU9300
4Gb of RAM
Intel Graphics Media Accelerator (GMA) 4500MHD (shared memory) - this chipset runs HD vidoes okay in LMDE Xfce, sometimes a little bit jerky at 1080.
Never locked-up in horrible, nasty, boringly slow, 32 bit Windows that the manufacturer installed.
Never locked-up in over 18 months running a 32 bit fork of Mandriva.
This must be a graphics bug relating to Debian.
I hope it gets fixed soon as I really like Linux Mint, much more so than the unsupported Mandriva derivative I was running previously,
