Can't switch from graphics to console

[jyp]

Still no luck here; problem persists.
I tried

Code Select Expand


~$ chvt 1
Couldn't get a file descriptor referring to the console


I tried the same command as root; I get stuck with a dead desktop (like frozen) until I do ctrl+alt+F7 to get it functional again.

Always in a twin monitor setup of course.

Any clue?

Thanks

Hi jyp

my system is quit similar, but I use the intel driver

I guess that you don't have the same problem with the intel driver. Am I right?

The installation is pretty recent and it seems that the installer choose to use _modesetting_ in spite of the fact that, as in your case, the intel driver is installed.

However, I have no clue how to change the driver ;-(

have you tried

Code Select Expand

cat /etc/X11/xorg.conf.d/20-intel.conf

Section "Device"
    Identifier "Intel"
    Driver "intel"
    Option "DRI" "3"
    EndSection

[jyp]

Thanks @jure

The file _20-intel.conf_ doesn't exist on my system.
Should I create it and polulate it like yours?

I wonder why the install process didn't choose the intel driver in the first place. To be honest, playing around with the X setup makes me a bit uncomfortable. This system is my working computer, not a test machine. Nevertheless, not having access to a tty can be very very annoying sometimes.

jyp,

as an entry point for understanding the reason would be this:
