yesterday a performed a couple of updates and after that i have executed Janitor (from within ubuntu-tweak) to cleanup (incl. everything, also old kernels) my system (Xubuntu 12.04.2, running on a recent Dell Inspiron 15R, dual boot with windows 8, hybrid graphics ATI7670). This turned out to be a bad mistake, when i power on the laptop and select Xubuntu from Grub i still do see the xubuntu loading screen, but after that i end up at a command line login (tty1).
My first idea was that i maybe somehow broke the kernel, so i decided to reinstall it - but now change. Next, i have checked some log files (syslog, kern.log, Xorg.0.log), the kern and sys logs do look ok, but the Xorg.0.log gave me some errors. Maybe i should add here that iam using the AMD catalyst driver (12.10.5) to control my hybrid graphics setup. The error messages looked as follows:
Screen 1 deleted because of no matching confg section Unloadmodule "Intel" Unloading intel fglrx(0): Powerexpress: Integrated GPU is selected fglrx(0): Powerexpress: cannot start '/usr/lib/fglrx' no such file or directory
I guess thats the problem, anyone any idea what to do? My next step would be to reinstall catalyst from the commandline (any suggestions how to that the best way?). Since iam relying on this laptop a lot for work i would appreciate any help.
