Arch Problems and Solutions

ArchProblemsSolutions.txt

#These are not necessarily Arch specific, but issues and solutions I found while working in Arch

Problem #1:
Trying to mount a NTFS partition shared with Windows but getting issues about an unclean file system, or metadata kept in a Windows cache?

Solution #1:
run sudo ntfsfix /partition/path to try and fix the partition. May have adverse effects upon Windows should this be the installation partition of Windows.

Problem #2:
Ext4 drive refuses to mount with giving non-root write permissions despite explicitely adding read-write permissions to the mount in /etc/fstab?

#Solution #2:

Problem #3:
Xrandr sees connected displays, but doesn't utilize them automatically.

Solution #3:
Do something like the command below to add the display.
xrandr --auto --output VGA-0 --left-of DVI-I-0

Problem #4:
Can't seem to give a program like Steam execution permissions on a mounted disk?

Solution #4:
In your /etc/fstab file, the permission modifiers user and users can actually imply the noexec permission modifier. Make sure to put the 'exec' permission after both of these.

Problem #5:
Wrong monitor considered the primary monitor?

Solution #5:
xrandr --output someOutputName(e.g. HDMI1, edp1, etc..) --primary

Problem #6:
Need to make something run on startup?

Solution #6:

Problem #7: Can't connect to extra monitors?

Solution #7:
Blow away all configs in /etc/X11/ and then xrandr --auto

Problem #8: You are missing the following 32-bit libraries, and Steam may not run: libc.so.6 

Solution #8:
steam --reset

Problem #9:
If lightdm doesn't start on boot, but can be run from tty

Solution #9:
add to the lightdm config file: logind-check-graphical=true
Basically your boot is so fast that the graphics driver isn't initialized yet.

Problem #10:
Time in Windows (dual boot) is always wrong

Solution #10:
Set the time in arch to use local datetime just like windows does.
timedatectl set-local-rtc 1 --adjust-system-clock
