Nemo's experience of the Abit AN-M2HD motherboard with Kubuntu Feisty Fawn
I posted here previously about getting a abit AN-M2HD motherboard for a new system I was building (my first one, I might add). It arrived over a week ago, but I only got the rest of the stuff I needed this Thursday. What follows is an account of building my machine, and installing and setting up Kubuntu on it. It also sort of functions as a review of the AN-M2HD for Linux users, and includes some tips for first time builders and Linux users. BTW, this is the first time I have used (K)ubuntu – previously I used Fedora Core 6.
My build is as follows:
I also bought a 2GB USB stick for backing up my files (Corsair 2GB USB Flash Drive Flash Voyager), a cheap USB to serial adapter (this motherboard has no serial port), and the Kubuntu Feisty Fawn 7.04 Live/Install DVD.

- Liteon LH-20A1H-487C 20xDVD±RW/DL LightScribe Beige, Black & Silver Bezels
I had most of the system put together by Thursday, and finished by installing the CPU/fan and DVD on Thursday afternoon. All in all it didn't take long to put together (though I did it in several stages). It took two people to install the power supply (a very tight fit in the case). The only problem I had was when screwing the motherboard into the case one screw cross-threaded and jammed (would neither tighten or lossen). When I tried to undo the screw the brass standoff unscrewed, and then the real fun began! So I had to remove the motherboard, and tried gripping the brass standoff with pliers, and unscrewing the screw, but it wouldn't budge, and I ended up stripping the cross from the top of the screw with the screwdriver! After a brief panic, and then a longer panic, I got someone to clamp the standoff with some chunky molegrips (not easy when you are millimeters from delicate electrical components) while I managed to loosen the screw with a pair of pliers. I had serious problems with many screws cross threading, though none jammed as badly as that one. It seems that some screws fit nicely in some standoffs but others would crosssthread easily – I managed to pair up each of the screws with a matching standoff before reinstalling the board. In future I would check this beforehand, and I would also have bought a nutdriver to tighten the standoffs so they don't undo when loosening a screw. You live and learn.
Despite advice to the contrary I fitted the memory and CPU after installing the motherboard. I had no problem with this, though inserting the memory took some effort, and the board creaked a little. I'm far too impatient, and when I got the board and case a week before the memory and CPU decided to go ahead anyway. I guess this can be risky, and the motherboard could crack – so be warned!
The manual with the Coolermaster case is next to useless (too simplistic for an expert, not detailed enough for a beginner), but connecting the cables was easy enough. The only awkward connection was the front panel audio, which had separate sockets for each wire. Luckily the sockets are labelled clearly enough. The only other thing to note is that the front panel firewire connector on the board is at the back, and the wire in the case is only just long enough to reach, and is pulled tight across the bottom PCI connector. Also, the case has a mysterious molex cable that comes from the font of the case (not the front fan) – this appears to be for a VU meter which comes with another version of the case. I'm not sure what the other ends of the wires are connected to, and left it unplugged.
I initially left the DVD and HDD (and monitor and keyboard) unplugged, just in case anything went badly wrong, and switched on the PSU (with the side of the case still open). A red LED lights on the motherboard to let you know the power is connected. Powered on from the front of the case (I've had serious problems with dodgy on/off buttons on store bought PCs – this one has a nice sturdy switch) and a green LED lights on the motherboard, the fans start up, and a few moments later there is a beep from the case's speaker. It POSTed perfectly first time! (This is my first build, so you'll have to forgive my over excitement.) I powered off, and finished connecting everything up. Then I had a go at booting Knoppix from a DVD – and it worked fine first time (though only using a basic graphics driver). Before installing Kubuntu I reset the CMOS and had a fiddle with the BIOS settings, and set the clock etc. It is worth noting that the manual for the motherboard incorrectly states the jumper settings for clearing the CMOS (left two pins for normal, right two to reset CMOS). It is actually the other way around (I knew this beforehand, incidentally), but is correctly labelled on the sticker Abit supply for sticking inside the case.
I then set about installing Kubuntu, which was easy enough – though I had to use the safe graphics mode to install (the X server failed to start from the DVD when I initially tried the default boot settings). Installation went well, and within about 15 minutes I had Kubuntu booting from my hard disk. I was able to connect to the Internet via my router fine from Kubuntu (though I couldn't get a connection from Knoppix), the on-board sound worked, and the graphics were reasonable given they were using a generic driver by default. Now I had to set about installing the nvidia driver (if only to get a higher screen resolution). Once you know how to do it, it is easy enough. I may have been able to install from the Kubuntu repositories, but my initial tests were met with failure, so I downloaded the latest drivers from nvidia's website (the GPU is very new, and so are the drivers). In hindsight, I may have been able to use the pre-packaged ones from Kubuntu, but I'll tell you how I did it. I followed Method 2 from this website – which seemed to work fine. I ran startx from the console, and (after editing xorg.conf) I got a nice 1280x1024 display on my LCD monitor. I ran glxgears, and 3D worked fine. So I rebooted, and then X refused to start – though it didn't crash, and I was able to get to a console using Alt+F1. startx refused to work from the console, with some error message about an API mismatch. I eventually managed to get X to start by running “modprobe -r nvidia” – but it would always fail on reboot. Googling found no solution. However after several hours of messing about I solved the problem. Despite having supposedly uninstalled the nvidia drivers supplied with Kubuntu I found they were still there. Running “modprobe -l | grep "nvidia"” showed four different versions of the nvidia driver running. I checked the date of the files and one of them was dated that day, the rest were older. So I modified the last line of /etc/default/linux-restricted-modules-common to read: DISABLED_MODULES="nv nvidiafb nvidia_new nvidia_legacy" – which would disable all the other versions of the driver but the one I wanted. At least that was the theory – and I turned out to be right! I rebooted and everything worked fine. I downloaded OpenArena, and had it running smoothly at 1024x768 without having to disable any features.
