[arch-general] Gnome-shell Compositing for full screen applications
by Mark Lee 27 Mar '14

27 Mar '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Salutations, I was recently running a test of the i3 windows manager and tried dolphin-emu. To my surprise I was able to play Wii games at full speed at 1080p resolution on my i3-2105 (Intel HD 3000) rig. I'm assuming this is due no compositing in i3. With that in mind, I was wondering if there was a way to make gnome-shell disable compositing for full screen applications.

[arch-general] browser and tty
by arnaud gaboury 25 Mar '14

25 Mar '14

Dear list, I decided to get rid of my mate DE and go i3. Before I am testing my settings on tty2 (Ctrl+Alt+F2) with a modify .xinitrc (exec i3). I have a weird behavior as regarding my web browser, could it be chromium or firefox. On my i3 config. I have this line: assign [instance="^chromium$"] → 1 Unfortunately, when I log in on tty2, there is no chromium being started. When I am back on tty1 (mate session), I find chromium being opened. Then, on tty2, if I start manually firefox, I can't as I am told "firefox is already running". Indeed it is but on tty1. It seems like web browsers are "attached" to my tty1. Is there any reason for this behavior? Shall I modify anything to start any web browser on tty2 ? Thank you for help.

[arch-general] Package conflicts
by Jonathan Arnold 25 Mar '14

25 Mar '14

I'm having a problem with the liteide vs gocode-git packages. liteide, which is an official Pacman package, has recently started to include the /usr/bin/gocode binary, which I have been using via the AUR package gocode-git (there is also another AUR package called gocode-bin but no pacman package). So now when I try to update I get an error: error: failed to commit transaction (conflicting files) liteide: /usr/bin/gocode exists in filesystem This didn't seem to be right, as I'm trying to install liteide, not gocode here. So I reported the problem: https://bugs.archlinux.org/task/39607 and it immediately got closed with the statement that AUR packages aren't supported so contact the maintainer of the AUR package. Well, as far as I can tell, there isn't much the maintainer of the AUR package can do if some other package is going to just put any old binary wherever it wants without saying anything about it. Shouldn't the liteide package at least say it provides 'gocode'? Or conflicts or something besides just letting pacman complain about a file that exists in the filesystem? Carrying this a bit further, how would it or should it work if I did want to keep using gocode-git, but also use liteide? -- Jonathan Arnold Webstream: http://hieronymus.soup.io If you want to go fast, go alone.

As root, enter the command 'su a' and not prompted for a password. 'less /etc/shadow' shows the password for the user. Interestingly, 'su a' results in the cursor 'pwd' to be the root home directory and not '/home/a'. > > Do you have the correct graphics drivers installed (xf86-video-*)?

[arch-general] [contribution] Pages from Arch Wiki optimized for offline browsing
by Jakub Lahwaacz Klinkovský 23 Mar '14

23 Mar '14

Hello all, I would like to present my most recent work: arch-wiki-docs-clean [1]. The package provides pages from the Arch Wiki, optimized for offline browsing, meaning they contain only the content, all MediaWiki navigation components are removed. While I was at it, I have also fixed another bugs found in the existing arch-wiki-docs [2] package: internal links with fragments (i.e. links to sections) are working. While there is still some work to be done [3], I think it is already much better than community/arch-wiki-docs. Downloading all pages from the wiki takes some time, so I have a package pre-built for you: [4]. Alternatively, you the HTML pages are dumped into 'dump_html' branch on Github (the PKGBUILD will use them by default). I will appreciate any feedback as well as suggestions for future development, I hope somebody will find it useful. Regards, [1]: https://aur.archlinux.org/packages/arch-wiki-docs-clean/ [2]: https://www.archlinux.org/packages/community/any/arch-wiki-docs/ [3]: https://github.com/lahwaacz/arch-wiki-docs/issues [4]: http://lahwaacz.sh.cvut.cz/ -- jlk

[arch-general] user management error
by message 23 Mar '14

23 Mar '14

Readers, A previously existing /home directory was mounted into the file system during the installation process; this directory contained files in a directory 'a'. A user was created from the root user account: useradd -M -p [password] -s /bin/bash [username'a'] After reboot, the system is restarted as root because the user 'a' is stated to not exist. The command 'cat /etc/passwd' reveals a password 'x', but this is not the password that was entered. How to solve this error?
