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 screenCtrl-Alt-BS to get out)
    • (Solved) Add acpi_osi= to /etc/default/grub (see guide N550JV)
  • Issue — NVidia GT750M card not detected.
  • 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)
  • IssueMinecraft — 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 DoMinecraft — Do we get more FPS if we disable compiz (or any compositor, like metacity)?
  • IssueBluetooth — Bluetooth sometimes not active, even with nvidia disabled
  • sudo modprobe -r aht3k; sleep 1; sudo modprobe ath3k # work-around - NOT WORKING
  • 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.
  • IssueMinecraft — 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)
  • To Do — Backup
    • Backup Windows Rescue / System Image DVD (to mnemosyne)
    • Backup Restore / Recovery partition (to mnemosyne)
    • Backup current windows partition (locally)
    • Backup partition table, EFI partition, etc.
