Hello! After installation of Ubuntu 13.04 on my new laptop I got error message “The system is running in low-graphics mode”. After some attemps to start x-server and install drivers, I tried to install nvidia-325 proprietary drivers and bumblebee. But it still prints this error message. Deinstallation of bumblebee and reinstallation of drivers was not helpful.
I also unsuccessfully tried nvidia-current, nvidia-304, nvidia-325,310 from two different repos, 319 official from Nvidia Web-site, and even 3.9-rc8, 3.10.10, 3.11 kernels.
After a few days of torment the system was surprisely started without error mesage, but Nvidia card still not works.
This is my Xorg.8.conf output
This is my dmesg output
