I have a Toshiba U840W laptop upon which I want to install Mint 14.
The U840W is a peculiar beast with a wide screen (1792 * 768 pixels at 60Hz).
Intel i915, 4000 HD, Mesa 9.0.3, X.org 1.13.0, GLX version 3.0.
Any flavour of Mint has the following problem. I have been over a lot of forums looking at Intel related graphics issues, tried a lot of things, all to no avail.
Here is the problem:
Grub bootloader displays, text is readable.
Select the bootload, screen goes black, pause and them the login screen is displayed.
The trouble is that the screen/display is covered with lines, mostly vertical, mostly shades of white and grey, the occassional bit of colour.
The login box shows and I can read a very difficult to read "Linux Mint".
The area for username and password is white so enter them and into the desktop. Same sort of display, vertical lines mostly grey with flecks of colour.
Can see the icons.
Shut the lid on the laptop. Count to 5, open the lid and the desktop displays correctly and and once past the password prompt everything works beautifuly.
So whats wrong, looks like somewhere in the boot process the graphics are not set up or set up incorrectly and then get set correctly on the lid close/open.
I have tried the "nomodeset", i915.modeset=1", and setting the GFXMode in "grub". No improvement.
Looked at regressing the intel drivers from 9 to 8 (get key errors on that one).
Any ideas/directions/suggestions/whatever appreciated, Ian
