[Resolved]Archlinux - KAG don't work

Zohran · 2017-01-22 16:05:54

Hello, sorry for my bad english, i'm french

I have problem with KAG in AUR when i start it:

I have been searching for a while on the net but I have not seen any information about this bug.

Hey Zohran,

I am no expert (by far), but i guess it has to do with starting it as root. There is no running X-server for the root-user and so the game does not know where to show itself.

Why do you explicitly start it as root though? Most of the times there is no need to do that.

Thank you for your answer. In fact if I launch in root, it's because that it doesn't pass without:

You might want to try running it using gksu or gksudo. They are appropriate tools for running GUI applications as root.

Moving to AUR Issues

Is your user in the games group? The PKGBUILD changes ownership of some files to root:games. Not sure if it will work, but worth a try..

I tested and added my account to the group games but it does not change anything.

I installed gksu and i tested it:

This is a bit unusual:

/dev/sda2 on /tmp type ext4 (rw,relatime,data=ordered)
/dev/sda3 on /var type ext4 (rw,relatime,data=ordered)

In general, I would expect those be tmpfs rather than physical devices.

ewaller · 2017-01-22 22:49:18

'Aucun fichier ou dossier de ce type' translates to 'No such file or folder'
A little confusing. /tmp does exist and should be writeable.

Any idea why you are using physical devices for tmp file systems?
I'm running out of ideas

Zohran · 2017-01-22 22:56:59

/ tmp is on a different partition because I have 2 hard drives, one HDD and one SSD.

But if it is not readable, maybe I have done wrong my installation?

Can I change that? Or is it irreversible?

ewaller · 2017-01-22 23:15:46

You can change it, all you have to do is change /etc/fstab. Usually /tmp is a tmpfs which (I believe) are RAM disks.

Can we see your /etc/fstab?

Zohran · 2017-01-22 23:20:43

Yes I can read it and change it to root. I give you the contents:

# 
# /etc/fstab: static file system information
#
# <file system>	<dir>	<type>	<options>	<dump>	<pass>
/dev/nvme0n1p2  /       ext4    defaults        0       1
/dev/sda1       none    swap    defaults        0       0
/dev/sda2       /tmp    ext4    defaults        0       0
/dev/sda3       /var    ext4    defaults        0       0
/dev/sda4       /home   ext4    defaults        0       2

What should I change? What is my error in fact?

ewaller · 2017-01-22 23:24:53

To be honest, I would comment out the /tmp and /var lines. Let systemd handle them and treat them as tmpfs.

Zohran · 2017-01-22 23:35:10

Sorry but I still need to learn
Like this ?

#

Are you sure /var usually is or even should be a tempfs?

@Zohran: No. This is your opportunity to read the mount and fstab manpages and the fstab wiki article. You might also want to research, what "to comment out" means. It might also be a good idea to double check recommendations, because even an experienced user like ewaller might suggest to remove a /var mount line without further steps out of the blue at some point. If you unmount /var from where ever it is now, it will be a plain folder called "var" in where ever "/" is being mounted, but it won't contain the files.

Zohran · 2017-01-23 01:27:23

I have already read these pages, but honestly I do not know what to do to solve my problem.

That's why I ask for help

I tried putting my scores in type tmpfs, but it does not work. Pacman can not find the partitions anymore.

Scimmia · 2017-01-23 01:32:44

/var should definitely not be tmpfs. Don't comment that out or things break.

ewaller · 2017-01-23 01:50:19

Damn. Sorry about that. I was thinking /run but I typed /var. Even that is not correct.

My apologies.

It's time to boot your install medium and fix the mount point by reverting the fstab. If you're unsure about the syntax, mount the partitions manually and use genfstab (the same way you did while installing Arch). Also remember arch-chroot, in case you need it. Fixing Arch is a lot like installing Arch.

Zohran · 2017-01-23 10:53:28

Thanks a lot for your help. But what I do not understand is what I have to do with my partitions ... Could you be more precise?

Revert your fstab to the state it was before you damaged it. That should be enough to get your system back on track.

Zohran · 2017-01-23 16:09:33

Like that ?

#

/dev/nvme0n1p2  /       ext4    defaults        0       1
/dev/sda1       none    swap    defaults        0       0
/dev/sda2       /tmp    ext4    defaults        0       0
/dev/sda3       /var    ext4    defaults        0       0
/dev/sda4       /home   ext4    defaults        0       2

I had already delivered it as at the beginning.
But it was I who configured the fstab file at the origin. I thought you were telling me I had misconfigured it.

So I leave it like that or not? Because it does not solve my problem with KAG anyway

Awebb · 2017-01-23 19:05:50

Yes, leave the fstab be for the time being. Just for your information, /tmp is "by default" (whatever that means on Arch) in a tempfs, all you need to do to make it so, is delete the line containing /tmp and reboot, it will automatically be mapped to /tmp. Your fstab is not broken, it's just unusual, so ewaller wanted to streamline your setup to make it easier to squash that bug. I'm not familiar with KEG or Irrlicht, I only wanted to point out, that /var is not as volatile as it seems.
