Re: Graphics Resolution- Upgrade /Blank Screen after reboot
Hi, MAFoElffen, Its me, bogan, in trouble, again. Another long story, be patient.
With considerable help from you, I was running Vista in sda1, Ubuntu 10.04, 2.6.32-28 in sda6, and 11.04, 2.6.38-8 in sda8.
10.04 was fine, and 11.04 acceptable, except Startup Manager would not alter the default in the Grub menu, and occasional problems with WiFi connections.
Then Update Manager had problems in updating linux headers. I tried on several occasions but it gave error messages saying the header update could not be installed, something about dependencies.
Computer Shopper HelpFile said this was due to the mirror being used for the download, and to use the Edit menu of Software Centre to select Best Source and try again. I did this but with the same result though with a different header update. Finally in frustration I tried the offer of an update to Ubuntu 11.10. ----Disaster!!
During the install and at the end before going to CleanUp, it showed several error2 messages, two for Headers as before, one for GDMSetUp and one for GrubPC. It then opened a Ubuntu 11.10 screen with a window for entering a password and at the top right a Login Screen Icon - a relic I had set up in 11.04. Clicking this produced an error saying 'gdmSetUp no such file or folder'. When I entered my password it restarted with the Grub Menu as before, unchanged; but though Vista and 10.04 booted OK, 11.04 gave a black screen with no response.
I decided that I did not want the bother of mounting 11.04 from 10.04 as it almost certainly needed a reinstall - I thought.
So I updated 10.04. Unfortunately, in updating to header 188.8.131.52 it reinstalled the old Grub 1.98-1ubuntu12 so the grub menu is now in Low-Res white text on a black background, instead of gold on magenta.
Later I decided to look further into things and found if I selected the 11.04 recovery mode the black screen was responsive to Ctrl-Alt-F1&F2 giving me a Ubuntu11.10 welcome and a TTY prompt - not a login - and
opened an 11.10 screen but with an 11.04 style login window.
sudo service gdm start
Eventually ( before I saw your 715 Post ) I found that if I edited the 11.04 grub menu Linux/boot line to delete the 'vt.handoff=7' and added 'text', leaving in the 'VGA=795', after a thirty second black screen it booted directly into the graphics 11.10 login screen.
( Using the '--verbose single' edit you suggest in post715, gives several screens of text and a root prompt - not a login - from which opens a blank magenta screen with an 11.04 style login window.)
Most things seem to work OK, except for the login screen Icon, and there seems to be no way to create application Icons or Panels and Launchers with a right mouse click, as there was in 11.04. Running update-grub or Startup Manager showed not only 11.04 2.6.38-8 to be present but also 2.6.38-10, & -11 and also 11.10 3.0.0-12, though none of these show in the grub menu. Edit: After a cold reboot into 10.04 and running update-grub several times, the above entries now show on the grub menu; but 3.0.0-12 only gives a black screen with a small flashing cursor.
What do you advise?, is it worth persevering with this, reinstalling GDMSetUp, Grub2 and GrubPC? Would I need to purge all the false headers and reinstall them?
Edit: See note above, ( How can I get past the need to edit the Grub menu entry? Using gedit to alter /etc/default/grub has no effect.) No longer applies!

Reason: Delete wrong header reference 2.6.38-12, Note re update-grub added.
