ctrl alt F1 shows only a blank screen and no tty login

Asked by u4ear on 2015-04-29

14.04.02 running ATI graphics card HD7990 with drivers from ATI.

lightdm login works normally but CtrlAltF1-6 shows only a blank screen

it should show the tty login prompt.

If i uncomment the #GRUB_TERMINAL entry in the grub startup script and sudo update-grub

The screen remain blank.
CtrlAltF7 returns to lightdm - as normal.

If i leave the #GRUB_TERMINAL entry as default - then CtrlAltF7 fails to return, the keyboard does not work (even caps lock) and a power cycle is needed to recover.

Hope this finds a solution.

I suggest you report a bug.

What are you wanting the low TTYs for? You can press CTRL + ALT + T and get a terminal....

u4ear (ubuntu-u4ear) said : #2

In the past if the xsession becomes locked ctrl alt F1 can be used to get a low tty and kill a process.

If you need to update GPU or stop X / gdm or lightdm.

Does that explain ?

Can you help with this problem?
