i guys I have some problem with my HP 3150sa laptop (ubuntu 10.10 64 bit). When I ask vga switcheroo (from UCC) to switch to high perfomance graphics card it logs me out and in again and I loose my compiz. I checked UCC>HARDWARE>System information>display after the switch which doesn't show up the ATI card at all. I tried this link but no joy http://asusm51ta-with-linux.blogspot.com/ please find the following info rmp@ocn:~$ uname -r 2.6.35-24-generic rmp@ocn:~$ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02) 01:00.0 VGA compatible controller: ATI Technologies Inc Manhattan [Mobility Radeon HD 5000 Series] rmp@ocn:~$ dmesg | grep switche [ 13.504555] VGA switcheroo: detected switching method \_SB_.PCI0.GFX0.ATPX handle [ 13.506253] vga_switcheroo: enabled rmp@ocn:~$ cat /sys/kernel/debug/vgaswitcheroo/switch 0:+wr:0000:00:02.0 1: wr:0000:01:00.0
