I got the infamous The system is running in low-graphics mode error after installing Zorin 9 (based on Ubuntu as far as I know), but the interesting quirk is that if I don't install it but select Try Zorin when booting from the installation DVD, it works fine. Graphics, sound, wireless, everything. However, after I installed it, none of them work.When the error message appears, pressing CTRL+ALT+F1 doesn't open the terminal, it instead leads to a complete freeze.The only way to access the terminal was through selecting root in the recovery menu, but I couldn't do anything there, I assume the file system wasn't mounted the correct way.Trying to do anything with apt-get leads to the following error message:W: Not using locking for read only file /var/lib/dpkg/lockE: Unable to write to /var/cache/apt/E: The package lists or status file could not be parsed or opened.The machine is a Lenovo IdeaPad 300-15IBR, with Intel HD Graphics.
The old The system is running in low-graphics mode error in Zorin 9, but it works fine with the live DVD
