-====== Boot - Fix Boot Problems ======
-===== Black screen after installation of the closed non-free Nvidia driver =====
-The latest kernels have moved the video mode setting into the kernel. So all the programming of the hardware specific clock rates and registers on the video card happen in the kernel, rather than in the X driver when the X server starts.
-This makes it possible to have high-resolution nice looking splash (boot) screens, and flicker-free transitions from boot splash to login screen.
-Unfortunately, on some cards this doesn't work properly and you end up with a black screen. Other problems may be a big boot delay, sometimes coupled with a loss of the configured desktop wallpaper. In particular, some closed non-free Nvidia drivers appear to be affected.
-Edit **/etc/default/grub**.
-<file bash /etc/default/grub>
-GRUB_CMDLINE_LINUX=""
-</file>
-Replace it by this line:
-<file bash /etc/default/grub>
-GRUB_CMDLINE_LINUX="nomodeset"
-</file>
-Save the modified configuration file and close it.
-Then run:
-<code bash>
-sudo update-grub
-</code>
-Finally, reboot.
-===== The screen resolution is not right, after installation of the closed non-free Nvidia driver =====
-<WRAP info>
-**Note:** the following applies only to Nvidia graphics cards running on the Nvidia restricted driver.
-</WRAP>
-<code bash>
-sudo apt-get install nvidia-settings
-</code>
-Then type:
-<code bash>
-nvidia-settings
-</code>
-Now you can configure your screens properly, with this handy tool from Nvidia. As follows:
-- Click on "X Server Display Configuration" (in the upper left)
-- On the right: click on the tab Display (probably open already)
-- Resolution:click on the arrow after "Auto"
-- Choose the screen resolution that you want
-- Click on "Save to X Configuration File"
-- Click on "Save and exit"
-- Do a full reboot of your computer. Now the screen resolution should be right.
