• Google query "ubuntu asus n550jv"

Issues

• Issue — Fn-F2 (WLAN / Bluetooth switch) and Fn-F5/Fn-F6 (screen brightness) do not work.
• (NOK) Add acpi_osi='!Windows 2012' to /etc/default/grub (see [1], and also [2], [3], [4]) — Fn-F5/F6 still do not work, but Fn-F2 does work now!!!
• (NOK) Add acpi= to /etc/default/grub (as per [5]) — Does not work either (even got black screen → Ctrl-Alt-BS to get out)
• (Solved) Add acpi_osi= to /etc/default/grub (see guide N550JV)
• Issue — NVidia GT750M card not detected.
• Install xorg-edgers (see [6])
sudo apt-add-repository ppa:xorg-edgers/ppa sudo apt-get update sudo apt-get install nvidia-331 nvidia-settings-331 nvidia-prime
• Reboot. Multiple issues from apport (→ disabled now)
• Nvidia card works with accelerated OpenGL, but keyboard is stuck to US layout, and Bluetooth is lost. Fonts are not rendered as usual it seems.
• Purge xorg-edgers to see if we can revert back to previous situation:
sudo ppa-purge xorg-edgers sudo apt-get autoremove nvidia-prime
• (Solved) Install bumblebee and nvidia drivers v319 (see guide N550JV)
• Issue — Minecraft — Graphics glitches, missing limbs on intel card.
• (NOK) Changing settings, to no avail: Graphics: Fast / Fancy, View Bobbing: ON / OFF: Advanced OpenGL: OFF/Fast/Fancy
• (NOK) Tried these VM, and they have glitches: OpenJDK 7 64, Oracle JDK 7 64.
• (NOK) From [7].
  • Run MC with -Xmx512M
  • Run in fullscreen
  • OpenGL / Multicore settings: Smooth FPS: On, Load Far: Off, Chunk UpF: 2, Lazy CL: On, Smooth World: On, Preload Chunks: Off, Dynamic Updates: On
  • Setting priority of proSeems to workcess java to high (aka sudo -k nice -n -5 su -c "..." -USER, see [8])
• (NOK) Disable compiz before launching minecraft (see [9])
sudo apt-get install metacity metacity --replace && ./launch-minecraft-now && unity --replace &
• Check more solution from google query "optifine missing limbs" — ...
• (Alt. solution) Disable OptiFine
• (Solved) — use NVIDIA OpenGL (via bumblebee)
• Issue — Image really dark
• Use xrandr (see [10]):

xrandr --output eDP1 --gamma 1.4:1.4:1.4
xrandr --verbose

• Q? — How to make that settings permanent (setting is lost after quit / restart)?
  • I could make a custom script per seat, that is run right before launching minecraft.
• To Do — Minecraft — Do we get more FPS if we disable compiz (or any compositor, like metacity)?
• Issue — Bluetooth — Bluetooth sometimes not active, even with nvidia disabled
sudo modprobe -r aht3k; sleep 1; sudo modprobe ath3k # work-around
• Done — Check BIOS version and upgrade if necessary (see [11])
• We have version 204. Updated to version 207
• To Do — Check install guides above.
• To Do — Try latest nvidia drivers from xorg-edgers.
• Issue — Minecraft — FPS stuck at 60 FPS.
• Solved — This is due to vsync. Disable it with env. var vblank_mode ([12]):
vblank_mode=0 java ... # Only for one app echo "0/SyncToVBlank=0" >> ~/.nvidia-settings-rc # ... or for all apps
• (or uncheck the nvidia-settings option at X Screen 0 / OpenGL Settings / Sync to VBlank)
