Ah.. I get it now.
So I'll create a thread in an ubuntu forum and post the link here.
Let's hope that they'll fix it.

Using the "Synaptic Package Manager" I only found "x11proto-dri2-dev" which sounded like any of those you listed.
Sorry if I'm doin something wrong. I'm really new to linux.

Had this issue, resolved it by upgrading everything related to graphics to their git versions. However, with ubuntu, I'm not sure how (or if it's possible) to do it with apt (I use arch, and therefore pacman). You'd have to ask someone more knowledgeable on Ubuntu for help with that.

When asked for hardware, chipset would have been nice, but assuming you're using the 945GM like me (or card name GMA950), then the issue is resolvable by upgrading mesa, intel-dri, xf86-video-intel, dri2proto, and the various dependencies for the above all to their git versions. You don't need the git version of xorg, but you'll need the newest released one (which I don't believe is the one Ubuntu ships with).

Finally, there was still problem running my compiled client after all of that, so I had to install in wine, and it worked fine there.

Enjoy

So.. 'TL;DR' try again with wine or search for a command which gives me intel about my chipset and post it here?

Ok. When I start creating my character it's all good cept I can't see the 3D model of the race.
I cba caring at that time and kept going. Everything seemed alright and i "uploaded" my character.

Then when I try to start the game the window freeze at some parts.. The UI is visible but I can't see my character or any NPC's.
I read something about a guy who had the same problem in another topic, but I think he managed to fix it somehow.

I'm a linux-newbie and a PS newbie. So please help  
Also, I'm running on a laptop, which makes hardware identifying kinda hard. Feel free to give me terminalcommands and such which helps me figuring out my components  


--Edit--


I printed it so you guys would get a clearer picture of it.
I dragged some UI-stuffs so you can see how I meant by freezing.

(The picture you see behind the UI is the loading picture.)

I installed Planeshift using wine. I got a R6034 error, but followed an step-by-step tutorial by a guy on this forum;

Hi,
as i had a lot of these random client crashes since 0.4.03, i tried to run the windows version of planeshift using wine on top of linux. and it worked! Here are the step by step instructions on how to install it:

If you already have wine installed, you can skip the steps 1-3.

1. Install the latest stable version of WINE using your distro's package manager
2. Install the package cabextract
3. Run WINE's configuration utility 'winecfg', it will create the directory ~/.wine/
4. Go into this directory and execute 'wget http://www.kegel.com/wine/winetricks'
5. Run the command 'sh winetricks vcrun6 vcrun2005 corefonts'. I'm not sure if you need a license of Windows to do this legally! I'm neither sure what exactly the winetricks script does; i didn't write it
6. Download and install the Windows version of PlaneShift into wine. To run the installer type 'wine name_of_the_installer.exe' in the directory where you downloaded it.
7. Run your new PlaneShift client: Go to '~./wine/drive_c/Programs/PlaneShift' (or however these directories are called on your PC) and execute 'wine psclient.exe'

You can even symlink your ~/.PlaneShift directory to the Windows version's PlaneShift directory to use the same settings and logs with both clients.

The WINE client runs stable for me, Thob from my guild uses it too. However, we both have a completely transparent GUI under wine. That means, you can't see any window backgrounds and buttons without text. But it doesn't crash

I don't know if that works for everyone, try it ON YOUR OWN RISK!

Everything went smooth and shit. But when I finally got it up and running it had the same non-refreshing error as the non-wine verision.
This is getting quite irritating.
