Catalyst on Linux 3.12

ArchLinux likes to freeze on me also when the PC is idle and I lost about two hours of joyous creative work (it's no fun done the second time). So I switched back to Manjaro (openbox flavor) because it was the best usable distribution in my view.

Finally, when AMD started to feel some love for the linux OS, apparently an update of the Xorg server broke the comatibility with catalyst. I am still not sure if this is in any way related to my freezing-on-idle problem but for now my system seems to require kernel 3.10 and xorg 1.14. Applying a blind update could be fixed using this post. However I needed to remove all catalyst and xorg packages and reinstall xorg completely.

Once xfce would start properly again, I used the provided installer for proprietary drivers.

ArchLinux with XMBC on the Odroid-XU

Yay, I finally got around to setup my odroid towards the direction I originally anticipated. The goal is to have a dedicated home media server running in the living room while it is hooked to the router and accessible from the internet as an app server and possibly cloud service. A lot of jobs for the small board, but a Linux OS with hardware acceleration for video playback should pretty much do the trick.

So after some fruitless attempts with other Linux images (see further below for previous candidates) I came across this slightly pre-configured ArchLinux image on the odroid forums by user gripped which comes with XMBC.

On the eMMC I still have my Android 4.2 installed. I like to keep it there for now as some kind of fallback. To get ArchLinux running, I copied the extracted image using the supplied Win32ImageWriter (I just use it for USB sticks, too, now) onto an 8GB microSD card with my crappy USB1.1 SD card reader (takes pretty much forever10-20min). Flip the boot switches to ON-OFF and boot up the whole thing.

Curiously it would not start the first time and I had some quirks with it on some boots (just black screen) which were not related to the very touchy mini HMDI port. I am not sure if these problems are related to the issues I had with other Linux images in the past, but it seems to work now. Be aware that the HDMI cable should be unplugged before you connect the power cable. It supplies a dim current to the board (see red LED dimly lit) and the board refuses to boot when not coming from zero power. Right now I do not have it hooked to a display, so no problem at the moment.

Manjaro Arch Linux Configuration on my X41

Because I frequently come back to these commands and have not bothered automating these tasks, here is a list of common things I need with the Openbox setup on my Thinkpad X41:

xrandr –output LVDS1 –mode 1024×768 –output VGA1 –mode 1920×1080 –above LVDS1

TrueType Fonts under Linux

They are pretty and you get pampered with costly proprietary ones like Palatino Linotype by Windows. In case you are – like me – trying to write TeX under Linux and want to publish* the PDF result in one of those fonts, install one of the following packages:

$ sudo apt-get install texlive-fonts-recommended ttf-mscorefonts-installer

On Manjaro / ArchLinux the following set up everything I needed ready to go:

$ sudo pacman -S texlive-most

*DISCLAIMER: “publish” in this context is not meant outside of private use cases.

Backup mit partimage

Mit partimage kann unter Linux ein (bit-by-bit)-Backup einer gesamten Festplatte erstellt werden. partimage ist Teil der meisten Linuxdistributionen die vor allem als LiveCD oder Rescue-Systeme gedacht sind (so z.B. Knoppix)

Angeblich reicht ein Backup entweder mit partimage ODER dd um den gesamten Inhalt der Festplatte (inklusive mbr) zu kopieren. Im Netz gibt es dazu teils widersprüchliche Meinungen was die Bit-by-Bit Kopie und Geschwindigkeit angeht. Im Zweifelsfall empfiehlt sich eine Kombination der beiden Methoden, indem der mbr mit dd und der rest des images mit partimage kopiert wird.

Partimage wird leider nicht bei allen Linux Distributionen mitgeliefert, kann jedoch im Live Betrieb bei bestehender Internetverbindung nachinstalliert werden (im Falle von Ubuntu):

sudo apt-get install partimage

dd hat leider keine eigene Fortschrittsanzeige. Diese könnte mit dem Programm pv improvisiert werden, welches leider auch nachinstalliert werden muss

Die Anleitung basiert teilweise auf diesen beiden Artikeln zu partimage und dd.
