Ok I did stuff in the terminal and then the whole desktop except for the wallpaper disappeared. And because of my stupidity I ran the startx on root. Then when it did not work. I shut it down. When at start again on entering password I get black and back to login prompt. It is LUbuntu 18.04.
This question has been asked several times, but the solutions I’ve found always solve the problem in a different way.
On the remote machine (the one on which I want to run
startx), I have already
echo allowed_users=anybody | sudo tee /etc/X11/Xwrapper.config
When I ssh to the machine and run
startx;, I get the error,
Fatal server error: (EE) parse_vt_settings: Cannot open /dev/tty0 (Permission denied)
I added myself to the
tty group after which the error is
Fatal server error: (EE) xf86OpenConsole: Cannot open virtual console 2 (Permission denied)
Speculating, when I log in to the machine locally,
getty (running as
root) assigns ownership of
tty0 to my user, and this is sine qua non. How can I make this assignment happen without typing my username and password on that virtual terminal? Maybe I can send keystrokes to the virtual terminal? Maybe I can
chown the right files so that I can own it?
Of course this is a “XY” problem. The real problem is: when I’m away, I would like to log into the machine (e.g. after a reboot) and turn on its monitor (a projector in this case) so that my family can watch movies on my profile without knowing or having to type my password.
I am relatively new to Linux and I have installed Linux Mint version 18 on my PC. In the past, I have been able to get the desktop to launch by typing
at the terminal. After I did a few upgrades, this command stopped working. I get an error message
modprobe: FATAL: Module i915 not found in directory /lib/modules/4.4.0-145-generic
Fatal server error: (EE) no screens found (EE)
I am not sure what this means. I browsed the web and I guess it has something to do with the Intel Graphics driver. I am stumped. Any help would be greatly appreciated. Thanks in advance.
Help, I am stuck in a login loop with Ubuntu 18.04. I already checked the permissions/ownership of the .Xauthority .ICEauthority and /tmp folder. I tried setting to from lightdm to gdm3. I am still stuck in a login loop.
I also tried running startx using the terminal logged-in as the user but it just ends in a blank screen. What are the options that are possible for me and how can I diagnose this? I also tried looking at .xsession-errors which is just filled with setting environment variable message and no error message.
