Last night I spent hours configuring Ubuntu and Installing Dependencies, programs and God-knows-what for a new Hobby Project of mine, Pupil.
It was a clean installation of Ubuntu 13.10 in Parallels 9 on my new Macbook. I had invested too much time installing pupil, only to find that the display drivers or GTK or something had been corrupted. This was the second time I was booting ubuntu and had been slapped in the face by this:
Could not switch the Monitor Configuration could not set the configuration for CRTC 80
I restarted it, but received the same error. The login screen was perfect, mind you; The error presented it self only after logging in. There was nothing else; No Icons, no Menu bar, no Unity. I googled for hours and tried everything I could; Using xrandr, Editing xorg.conf, Running Parallels Troubleshooter and so much more. In the end, I was somewhat able to restore my installation by reinstalling my Parallels Desktop Tools.
These are the exact steps I followed after logging in:
Control + Alt + F1
- In the full-screen terminal, login with your credentials
- In the Parallels Desktop Menu, select Devices > CD/DVD 1 > Connect Image
- In the new Finder dialog, browse to Applications > Parallels Desktop > Contents > Resources > Tools > pri-tools-lin.iso
- Now back in your terminal screen, type the following commands:
sudo mkdir /media/cdrom sudo mount /dev/sr0 /media/cdrom cd /media/cdrom sudo ./install
Parallels Tools’ installation will begin. Go through the steps and complete
the installation. After that, reboot using:
$ sudo reboot
If everything went fine, you would at least be able to see your desktop. In my case, there was no Unity Sidebar or the top Menu Bar; But it’s still something. Maybe installing Gnome would help.
Lesson: Make regular Snapshots of your OSes in Parallels
