Public bug reported:
I installed ubuntu9.04 (later I tried i386,x64,kubuntu , liveCD and DVD, and
the bug remained), with my lenovo thinkpad T400 switchable graphic card
enabled, os detectable yes, and all work fine. Only sometimes system use
internal GPU, sometime use ATI, cause the find hardware driver sometimes report
ati driver not installed, sometimes no driver detected.
But after I installed the restrict driver for ati, or I direct download the
latest 9.4 driver from amd and install it (yeah, I tried many times, about
reinstall my *bnutu tens of times) and enable it and reboot, Xwindow can't
start, screen display something( sorry my english is poor I can't exactly
describe it , look like screen crashed) no cli, no CTRL_ALT_F1. I also tried
safe mode auto fix X, after autofix the screen turned 3 times which I think
xwindow restart 3 time and remain blank screen for ever. Also safe mode cli
remove fglrx*, none of them works , have to reinstall.
Until finally, I go to BIOS ,disable switchable graphic card, disable os
detectable, It works fine.
