<ul>
<li> '''Issue''' — Fn-F2 (WLAN / Bluetooth switch) and Fn-F5/Fn-F6 (screen brightness) do not work.</li>
* ('''NOK''') Add <code>acpi_osi='!Windows 2012'</code> to ''/etc/default/grub'' (see [https://help.ubuntu.com/community/AsusZenbookPrime], and also [https://bbs.archlinux.org/viewtopic.php?id=147804], [https://bugs.freedesktop.org/show_bug.cgi?id=45452], [http://msdn.microsoft.com/en-us/library/windows/hardware/jj159305.aspx]) &mdash; Fn-F5/F6 still do not work, but Fn-F2 does work now!!!
* ('''NOK''') Add <code>acpi=</code> to ''/etc/default/grub'' (as per [https://wiki.debian.org/InstallingDebianOn/Asus/N750JV/Jessie]) &mdash; Does not work either (even got '''black screen''' &rarr; {{kb|Ctrl-Alt-BS}} to get out)
* ({{green|'''Solved'''}}) Add <code>acpi_osi=</code> to ''/etc/default/grub'' (see guide N550JV)

<li> '''Issue''' — NVidia GT750M card not detected.</li>
* Install [https://launchpad.net/~xorg-edgers/+archive/ppa xorg-edgers] (see [http://ubuntuforums.org/showthread.php?t=2189994])
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'' (&rarr; 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
* ({{green|'''Solved'''}}) Install ''bumblebee'' and ''nvidia drivers v319'' (see guide N550JV)

<li> '''Issue''' — '''Minecraft''' &mdash; Graphics glitches, missing limbs on intel card.</li>
* (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 [http://www.mpgh.net/forum/422-minecraft-tutorials/716970-optifine-ubuntu-linux.html].
** Run MC with <code>-Xmx512M</code>
** 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 <code>sudo -k nice -n -5 su -c "..." -USER</code>, see [http://askubuntu.com/questions/178491/nice-command-without-root-privileges])
* (NOK) Disable ''compiz'' before launching minecraft (see [http://ubuntuforums.org/showthread.php?t=1741768])
sudo apt-get install metacity
metacity --replace && ./launch-minecraft-now && unity --replace &
* Check more solution from google query "''optifine missing limbs''" &mdash; ...
* ({{green|Alt. solution}}) Disable '''OptiFine'''
* ({{green|'''Solved'''}}) &mdash; use '''NVIDIA''' OpenGL (via ''bumblebee'')

<li> '''{{red|Issue}}''' — Image really dark</li>
* Use <code>xrandr</code> (see [http://askubuntu.com/questions/371630/change-contrast-gamma-in-external-monitor]):
<source lang=bash>
xrandr --output eDP1 --gamma 1.4:1.4:1.4
xrandr --verbose
</source>
* '''Q?''' &mdash; 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.

<li> '''Issue''' — '''Minecraft''' &mdash; FPS stuck at 60 FPS.</li>
* {{green|'''Solved'''}} &mdash; This is due to vsync. Disable it with env. var ''vblank_mode'' ([http://stackoverflow.com/questions/17196117/disable-vertical-sync-for-glxgears]):
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'')

<li> '''{{red|Issue}}''' — '''Bluetooth''' &mdash; Bluetooth sometimes not active, even with nvidia disabled</li>
[ 13.663135] Bluetooth: Error in firmware loading err = -110,len = 448, size = 4096
[ 13.663173] Bluetooth: Loading patch file failed
[ 13.663198] ath3k: probe of 3-5:1.0 failed with error -110
* Filed bug [https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1260825 1260825] in Launchpad (see also [https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1102622 1102622], [https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1024884 1024884], [https://bugs.launchpad.net/bugs/1237296 1237296]).
* Work-around: unload / reload ''ath3k''
sudo modprobe -r aht3k; sleep 1; sudo modprobe ath3k # work-around - NOT WORKING
* Might be due to interaction with ''libmtp'' [https://bugzilla.redhat.com/show_bug.cgi?id=1070287]. But uninstalling ''libmtp-common'' as no effect.
<li> '''{{red|Issue}}''' — '''Keyboard layout''' &mdash; BE layout not applied on login</li>
* Adding ''.xinitrc'' to setxkbmap be (to fix keepassx issue) &mdash; this might fix the problem, or more precisely hide the problem.

<li> '''{{red|Issue}}''' — '''Boot''' &mdash; Boot stuck right after grub. empty screen. no disk activity.</li>
* We can trigger disk activity 2x by pressing ''return'' key.

<li> '''Done''' — Check BIOS version and upgrade if necessary (see [http://support.asus.com/download.aspx?SLanguage=en&p=3&s=529&m=N550JV&os=&hashedid=dad5aYI8mC6sfoNV])</li>
* We have version '''204'''. Updated to version '''207'''

<li> '''{{red|To Do}}''' — Many errors in '''dmesg'''.</li>
[ 12.493360] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver
[ 12.493374] lpc_ich: Resource conflict(s) found affecting gpio_ich
...

<li> '''{{red|To Do}}''' — '''Minecraft''' &mdash; Do we get more FPS if we disable compiz (or any compositor, like ''metacity'')?</li>

<li> '''{{red|To Do}}''' — Check install guides above.</li>

<li> '''{{red|To Do}}''' — Try latest nvidia drivers from xorg-edgers.</li>

<li> '''{{red|To Do}}''' — Backup</li>
* 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.
<li> '''{{red|To Do}}''' — Install better temperature management from Intel, see [http://www.webupd8.org/2014/04/prevent-your-laptop-from-overheating.html]</li>
<li> '''{{red|Issue}}''' &mdash; The battery led is blinking orange. This usually indicates an issue with the Power Management unit in the laptop. See this post [http://ubuntuforums.org/showthread.php?t=2176915&page=3]. One solution apparently is to press the power button for at least 5-7 seconds until the PM unit is reset (led stops blinking). Another solution is to remove the battery, wait 10-20 second, and reinsert the battery; but this requires opening the laptop case.
<li> '''{{red|Issue}}''' &mdash; XBMC touch interface does not work in v13 Gotham RC1. Filed as bug [http://trac.xbmc.org/ticket/15184 15184].
