    reinstalling x server

    im running linux mint 17.3 rosa 64bit on a pc with amd radeon r7 250 graphics. when i start it up it says "failed to start the x server. It is likely that it is not set up correctly. Would you like to view the x server output to diagnose the problem?" i click on yes and it says "mdm: xserver not found: /usr/bin/X :0 -audit 0 -auth /var/lib/mdm/:0.Xau Error: command could not be executed! Please install the Xserver or correct mdm configuration and restart mdm." then it says "the xserver is not disabled. restart mdm when it is configured correctly." i then get greeted with a terminal login screen and when i log into that i can access a terminal but nothing else. i assume that i need to reinstall the xserver but i dont know enough about linux to work out how to do it for myself. i would reinstall the os but i have it heavily personalised and it has important data on it. thanks for reading and please help!!

    That got me to my normal login screen but it then comes up with a message "your session only lasted 10 seconds. If you have not logged out yourself, this could mean that there is some installation problem or that you may be out of disk space. Try logging in with one of the failsafe sessions to see if you can fix this problem" I open view details and it says "syndaemon: no process found.
    Mdm (1694): glib-critical: g_key_file_free: assertion 'key_file !=null' failed"
    I tried logging in with a failsafe sessions but this kept happening in a loop.

    how did you come to that situation?
    is it a fresh install?
    did it start after an upgrade? describe it?
    most x server errors are related to graphical hardware/drivers.
    so please post the output of
    lspci -k | grep -iEA5 'vga|3d'

    I got there by trying to remove and graphics driver but I have reinstalled the OS after a successful backup so this is irrelevant now. Sorry.
