Installing Debian on Toshiba Satellite C50D-1-133

Here i write how to install Debian on my new Toshiba laptop.

Debian Wheezy was not working. Wlan was not found, the graphic card not correctly detected. Using a backport kernel solved the wlan problem, but not the graphic to work. Even with firmware only the vesa mode were used.

Because this i decieded to use Debian Testing (jessie build date 19.06.2014).
At the bios i disable secure boot, and switch vom uefi to csm mode.

With the Debian installer i delete all partitions of Windows 8.1, and the uefi partition. After this the installer was not able to write the grub2 into the mbr.
So i start with a Ubuntu live-cd and uses gparted to change the partion scheme to msdos.
After this the installer was able to create the partitions.

The installation works good, wlan and lan are found.

After the installation i installed the packages firmware-linux-free and firmware-linux-nonfree with dpkg -i .
Now the graphic works fine.

Sometimes during boot the kernel shows no messages at the text-mode.
The screen only keeps black. The solution i found was adding "vga=791" to the kernel.

The brightnesscontrol did not work after installation. The screen always has the highest brightness. For this problem i had to add a kernel parameter too:

The /etc/default/grub file of this machine now looks like this:

GRUB_CMDLINE_LINUX_DEFAULT=”vga=791 acpi_backlight=vendor”

After this only updating the grub with grub-update.
