I tried it accordingly to:
No luck. Can someone who got this working post his configuration?
you can alternatively try this.
set up autologin with some user into Xserver.
then log in via ssh with the same user as is logged in Xserver. do not use -X
run any OpenCL/OpenGL application. any GUI windows should appear on screen.
IMHO this is the easyest way.
I logged in remotley and did:
sudo service gdm stop
sudo /usr/bin/Xorg -br -ac -audit 0
And it works. So it is a problem with the gdm custom.conf file.
Here is my solution:
1. Disable gdm via grub (I don't need gdm on a remote machine)
In /etc/default/grub set
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash text"
2. In /etc/X11/Xwrapper.config set
3. In /usr/bin/startx set
Login with ssh and run:
and everything should be fine.
