Note that this does not happen every time I switch users, only after about every 3rd switch. The only resolution I found for the freeze is a cold restart. My hardware is a Lenovo W500 laptop, with 2 graphic adapters. I disabled the ATI adapter in the BIOS, ubuntu thus only sees the Intel adapter. lspci reports it as: 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) Here is the adapter info from Xorg.log: (--) PCI:*(0:0:2:0) 8086:2a42:17aa:2114 Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller rev 7, Mem @ 0xf4400000/4194304, 0xd0000000/268435456, I/O @ 0x00001800/8 (--) PCI: (0:0:2:1) 8086:2a43:17aa:2114 Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller rev 7, Mem @ 0xf4200000/1048576 I found the follwing report in my Xorg.log, making me strongly believe the graphics adapter is the problem here.
