Public bug reported:
Hi,
After upgrading from 16.04 to 16.10 my multi monitor setup is unable to reach
login screen. Computer is Panasonic CF-52 on dock station with two external
monitors. The error says low graphics mode enabled.Used to work just fine in
previous distributions. the last error in the log file says: ScreenInit failed
for driver 0. I have Intel graphics.
Workaround found so far: boot laptop out of dock station, then dock it
and monitors are recognized no problem.
Troubleshooting done:
Reintsall Ubuntu from thumb drive - reinstall option: same results
Reinstall Ubuntu from thumb drive - clean install except for /home drive kept:
same results
Run X -configure: same results
Regards,
isotope
