Portal: Prelude triggered me to finally try out Portal under linux / wine. Actually the only games I played since I’m on linux are Urban Terror and … Peggle Extreme. 
Don’t laugh, it was a Steam test. 
And I didn’t have any space to install anything bigger. Until I bought that 0.5TB drive a while ago, still didn’t fill that one up, so today I decided to try it out under opensuse 11.0 with KDE 4.1 and wine 1.1.6. I somehow messed up my steam install under 10.3 and since I got 15GB free on my suse 11 partition and up to date video drivers (since it is also a kde 4 tryout install), this seemed like an ideal environment. Indeed, it actually went very smoothly.
- install latest wine from build service
- install iexplore gecko replacement by surfing to an url: wine iexplore http://winehq.org
- download steam msi (exe no longer needed!) and run: wine start steaminstall.msi
- see the update fail and resume it manually: nice -n 19 wine Steam.exe or wine steamTmp.exe SelfUpdate “Steam.exe” 14
- create a desktopshortcut from steam. you have to use kde 4.1 folderview if you actually want to see it
- run!
Some screenshots to prove
While framerate seems okay and my savegames and profile seem intact, I did experience some graphical glitch: when looking through portals, sometimes white flicker occurs. I didn’t investigate any further as it’s late enough.
