Here is the procedure that I used, it works fine (enjoy the QHD+ screen !!!)
(skip steps 1-5 if you do not have a SSD)
1 (for SSDs) Use the Debian disk just to boot the system and obtain a shell (I do not remember the exact option)
2 (for SSDs) I created a big partition in the whole disk, starting at block 4096 (default).
3 (for SSDs) I could not find the information on erase block size for the LITEONIT SSD anywhere,so I'm using the default parameters ( hdparm -I /dev/sda
reports model type, i.e. LITEONIT LCS-256M6S 2.5 7mm 256GB but I did not find erase block size information on the internet for this model)
4 (for SSDs) Create the filesystem: mkfs.ext4 -b 4096 /dev/sda1
5 (for SSDs) Restart installation, select manual partitioning, edit partition, set use as ext4
, mount point: /
, additional flags: discard, noatime
these flags are useful for SSDs, discard uses block erase capabilities of SSDs, and noatime prevents the system for recording last access time in every files.
6) First boot: edit booting options (using advanced mode from GRUB screen, select kernel, press e, remove load_video and add flags: nomodeset text
, then press F10. nomodeset
means that the console remains in text mode, and text
means that the system will not attempt to start X11 graphics mode (it seems that the shipped drivers cannot drive the ultra HD screen)
7) edit /etc/default/grub
, find the line GRUB_CMDLINE_LINUX_DEFAULT="quiet"
and replace it with GRUB_CMDLINE_LINUX_DEFAULT="quiet nomodeset"
8) add blacklist nouveau
in /etc/modprobe.d/blacklist.conf
(create the file if it does not exist)
9) update-grub
10) rmmod nouveau
11) aptitude install build-essential linux-headers-amd64 linux-headers-amd64-all
12) Install NVIDIA driver (load it from NVIDIA's website)
13) dpkg-reconfigure linux-image-3.13-1-amd64
(this re-creates the ramdisk that contains the device drivers, including the new NVidia driver, and re-initializes the grub boot loader). Note: use uname -a
to see the version of your kernel (and replace in dpkg-reconfigure
command accordingly)
14) restart the system: shutdown -r
Normally, it will boot in graphics mode (and you will see tiny tiny icons, there are far too many pixels in this screen !!)
15) To make screen contrast hotkey work:
edit etc/default/grub
, find the line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet nomodeset"
and replace it with
GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi_osi=\"!Windows 2012\" acpi_backlight=vendor"
then do:
update_grub
Just one thing that does not work: switching to text mode with Ctrl+Alt+F1 gives me a black screen, but Ctrl+Alt+F7 gives me graphics back. Same thing when the screen-saver blanks the screen (Ctrl+Alt+F1 then Ctrl+Alt+F7 gives me the screen back).
