Title: GLW_StartOpenGL() - could not load OpenGL subsystem HELP!
Post by: Imploding Whale on October 24, 2010, 07:43:45 pm
I just downloaded Tremulous 1.1 the other day, and it was working just fine. Then, all the sudden, it stopped working this morning and I get this weird message. "GLW_StartOpenGL() - could not load OpenGL subsystem". So, what do I have to do? I read the FAQ, and I have no clue how to do any of those things. Please explain to me step by step how to resolve this issue, I'm not very nerdy (No offense) when it comes to computers. Explain it to me as if I was extremely handicapped.

Thanks.

Assuming you haven't upgraded your graphics drivers in the last few days, then you probably set the resolution too high.

Find the tremulous link in the start menu (or desktop or whatever), right click on it, and select properties in the menu.  In the window that comes up there'll be a box labelled target saying something like "C:/Program Files/Tremulous/Tremulous.exe", add +set r_mode 4 to it, so it reads something like "C:/Program Files/Tremulous/Tremulous.exe +set r_mode 4", click ok and click on the link.  You need to repeat the process removing the +set r_mode 4 bit again if you want future resolution changes to stick.

I get a pop-up that says "Problem with short cut. The name.....specified in target box is not valid. Make sure the path and file name are correct." Anything else I could do?

I imagine the params need to be outside of the quotes, as they're there to allow spaces in filenames, at the moment windows is presumably looking for a file named "C:/Program Files/Tremulous/Tremulous.exe +set r_mode 4", so you need it to read "C:/Program Files/Tremulous/Tremulous.exe" +set r_mode 4

Doesn't windows use backslashes? As in: "C:\Program Files\Tremulous\Tremulous.exe +set r_mode 4"

Hmm, i have a feeling that you can use either, unless you're dealing with a command prompt, in which case i imagine forward slashes are still used for switches, which could cause a problem, oh, or would enclosing the path in quotes get around that issue even there?

Can someone with a copy of windows please step in and give a definitive answer? It seems as though we might just have a bunch of linux users with hunches here.
