Sounds like there was a graphics problem (possibly with the graphics driver) that caused a segfault the carried around the the bios/cmos, which affected a subsequent boot...

If you have a laptop --> Turn off > remove battery > wait 10 mintues > boot > enter Bios Settings > exit without saving > Boot.

If a desktop--> Turn off CPU and Monitor. > Turn off ATX power switch on PSU. If no switch, unplug pwer cord. > Unplug network cable, video cable and Monitor power cable. Plug everything back in and power up monitor and CPU. > Enter Bios settings, then exit. > Boot.

Can you get to a Grub menu? If you select Rescue Mode from the boot menu, will it boot into a failsafemode / low graphics? If so, if you go into system settings > additional drivers... can you install a driver?

If you go to a terminal session, what does this say about your GPU?


lspci -vnn | grep VGA

Please post your /var/log/Xorg.1.log

LOL! That's still okay... Just getting to that BIOS password prompt should be enough to clear the affected cache. <Cntrl><alt><del> from there should get you booting again.

Sidenote-- You may later what to clear your CMOS so you can either reset that password or to disable BIOS password setting. Desktop, laptop, different models- vary on how to do that.

Almost all BIOS have a jumper or reset switch to allow clearing
the CMOS which clears out the BIOS password. If you call the
manufacturer of the laptop, they should be able to tell you how to access the jumper or switch on your model. I bought an old desktop PC at a garage sale which had a BIOS password required.
I did the above procedure and was able to boot it without a
password prompt.

If it is a desktop, you just pull the cmos battery and jump the cmos clear pins for 10 seconds. If it is a laptop... then things are different.
