blank screen 2 secs after Thinkpad logo

#1 Post by winkoe » Tue Jul 14, 2020 11:43 am

Greetings to you,

Thinkpad W700ds. Installed systems are Debian and Kali Linux. At startup the expected Thinkpad entry screen appears for ca 2 sec. Blindly I can select either system. On Kali the secondary screen had been activated and there the (verbose) boot sequece is beeing displayed. I can log in and thereafter the secondary screen shows my Kali background color. Meanwhile the main screen remains black.

I go to sleep mode via Fn + F4. After wakeup via Fn the main screen wakes up for about two sec, and the goes black again.

With Debian the secondare screen had not been activated. However I can SSH from a separate machine and work on the terminal. From 'dmesg' I get no clue.

How should I proceed?
Thanks and watch your health.

Are you using lightdm? The fix is the following, create /etc/X11/xorg.conf.d/20-intel.conf and add the following:

Section "Device"
Identifier "Intel Graphics"
Driver "intel"
EndSection


Reboot your machine and all should work fine...
