The Second Life for Linux client has been in Alpha state for some time and I couldn't get it working with my Fedora Core 5 box, which has an ATI x700 card.

Now I've just downloaded an updated version and it worked.

After you've correctly setup 3D rendering for the ATI card you just need to download the Second Life client for Linux, I'm running version 1.13.2 (5), I found the link in the Second Life forum for the Linux client.

At first I had some problems with ALT + clicking but these threads helped me to get the problem solved.

The first thread tells how to disable using ALT + click in Gnome. I use KDE, there you find the relevant options going to Control Center > Desktop > Window Behavior > Window Actions. I changed the modifier key in the Inner Window, Titlebar & Frame to Meta (which is the Window key in my keyboard).

I also started Second Life with:

SDL_VIDEO_X11_DGAMOUSE=0 ./secondlife

After doing that I still had some issues with my camera and ALT clicking so I went full screen (View > Toggle Fullscreen or ALT + Enter) and things seem to be working fine now.

I can't teleport right now but I guess is just a temporal grid issue.

I hope this helps all linuxers out there to get into Second Life. By the way, I'm Mento Gamba, shoot me an IM while you are in-world.

Update: Bad timing! There was in fact a grid problem when I wrote this article; however, after it was resolved, I still couldn't teleport. The problem was that I was using a preview version of the Linux client which uses the Beta Grid. I grabbed a copy of the non-preview client, the one the link above refers too, and now I'm back on business.
