I will setup a Lenovo T410i laptop which has a nvidia grafic card. The laptop should use additioaly second monitor when in the docking station and of course expand the gui across both screens.
The (original) driver can't handle this - allways assumes both motiors are connected. So I installed the nouvea driver and get trouble with tdm.
Trouble from the nouveau driver is common with certain NVidia gfxchips.
Tdm starts and I see the clock for a short time and then tdm terminates and a text only terminal login is shown. When login and call "startx", I get a working trinity session and the crash report manager is shown.
So my question is "where can I look for error messages of tdm" or has some one else an idea or a solution for the problem?
For us to help with any detail we need to know which operating system version and hardware you have. These would help:
lspci -nnk | grep -A4 VGA (only tells about your video hardware) hwinfo --gfxcard (more detailed video hardware info) hwinfo --monitor (detailed display info) inxi -c0 -v6 | head -n20 (fairly comprehensive) ~/.xsession-errors (tde log) /var/log/Xorg.0.log (log of X server operation, also Xorg.1.log if it exists)
