Debian 10 x64

Linux pcname 4.19.0-11-amd64 #1 SMP Debian 4.19.146-1 (2020-09-17) x86_64 GNU/Linux

Intel Core i5-6200U

Intel HD Graphics 520

  1. After being unable to run xorg with startx on TTY1 added /usr/share/X11/xorg.conf.d/20-intel.conf:
Section "Device"
        Identifier "Configured Video Device"
        Driver "intel"
EndSection

  1. Logged in on default TTY7 with user1 with GUI (tried lightdm and sddm with KDE5)

  2. Logged in on TTY1 with user2 and run startx. Cinnamon runs well.

  3. Switched back to TTY7 and got black screen with blinking input cursor. In case with lightdm machine hangs. I can't switch back to TTY1 and only REISUB helps. In case with sddm there was cyclically switching between TTY1 and back.

The same was with Intel Core i3-3120M (Debian 8 and 10).

Tried to set uxa and blt options with no changes. On PC with nvidia videocard everything working perfect with Debian 8 and 10.

Syslog (don't sure this strings related to my problem directly):

What can be done to run different xorgs on different TTYs and switching between them?

  • Hi! What commands do you use to run xorg? Do you specify different display numbers? https://unix.stackexchange.com/questions/240093/running-more-than-one-console-x-session-with-startx-at-the-same-time – Roman Riabenko Oct 08 '20 at 09:07
  • `startx`. And `/home/user2/.xinitrc` with `exec cinnamon-session` in it. I does not specify different display numbers. Should I and how? – J. Yellow Oct 08 '20 at 10:23

To get a stable Intel driver I created /etc/X11/xorg.conf.d/20-intel.conf and defined:

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "AccelMethod" "sna"
   Option      "TearFree"    "true"
EndSection

Depending on your hardware the accel method could be "uxa" but I doubt it. (Old GPUs only) Before setting this, I had problems with LightDM, it crashed constantly.

In /etc/lightdm/lightdm.conf I configured the greeter:

[Seat:*]
greeter-session=lightdm-gtk-greeter
greeter-hide-users=false
session-wrapper=/etc/lightdm/Xsession

In the same directory the file lightdm-gtk-greeter.conf is needed. It should contain: (or any other theme)

[greeter]
theme-name = Adwaita-dark
icon-theme-name = Adwaita

  • Thanks for the answer! I've edited configs right like you write, but it does not help. And I have not `/etc/lightdm/Xsession`, so tried default option. – J. Yellow Oct 07 '20 at 19:57
  • Xsession might be crucial - but this is something which is solved differently on each distro. I've taken it from my arch linux session. But I'll look into another device, which has debian running. BTW- what do mean by "running different Xorgs" There is only one ;-) – kanehekili Oct 07 '20 at 21:17
  • I mean run to independent copies on tty1 and tty7. In debian there is default option `session-wrapper=lightdm-session` in `session-wrapper=lightdm-session`. And there are some [Xsession files in packages](https://packages.debian.org/search?suite=stable&section=all&arch=any&searchon=contents&keywords=Xsession). Should I try another Xsession, for example, from sddm? – J. Yellow Oct 08 '20 at 10:18
