Can't get Stellarium to run with my graphics card

[Merlin999]

Hi guys,

I can't get Stellarium to run on my Desktop PC. I can run it on my small laptop which will be more useful for stargazing at night, but I would like to be able to run it on the bigger screen on my desktop PC so I can have a good play around with it.

The error I have is with atioglxx.dll. I have researched this and found other people have had problems with older ATI graphics cards like mine. I am using a Radeon X800 graphics card with PCI Express. I have tried downloading a new driver for my card but this has made no difference. From what I can see the problem is with OpenGL.

I'd rather not have to buy a new graphics card unless absolutely necessary (my wallet is sulking after some serious astronomy overuse). I don't have any problems with any other software such as Adobe Photoshop, only with Stellarium.

I have posted a query on the Stellarium board, but I wondered if anyone here had a similar problem and had a possible work around.

I've not had any troubles with my ATI cards. What drivers are you running?

Thanks Revs

I am running version 10.2, (dated 24/2/2010). I've found that the X800 is now classed as a legacy software so only critical fixes from now on.

Which graphics card are you running at the moment?

I recently downloaded this from the disc on the S@n magazine. I found that it crashed if I opened it from the desktop link but not if I opened it from the start menu in no openGL2 mode.

It runs perfectly this way, as far as I can tell-then again it is the only way I have ever used it...

Thanks Perryellis, Yes I had seen the problem could be with OpenGL2. I've got to go get my kids form school now, but I'll give that a whirl when I get back. Let you know how I get on.

hi merlin999

have you tried runnig stellarium in no open gl2 mode

with stellarium ver 0.10.5 you have the choice in the program menu

sorry i see perryellis has the same idea

[Toadeh]

Start > Programs > Stellarium and run the no OpenGL2 option, does that work?

edit: sorry, above beat me to it

[Perryellis]

Great minds think alike and all that

[Merlin999]

Great minds think alike and all that

And indeed you all are great minds for that worked!! Thanks everyone, you are all stars;) :hello2:Do you have any idea what effect not using OpenGL2 has on Stellarium?

[Perryellis]

No idea!!!

[Merlin999]

Had a quick look and it seems to all work fine. I can't tell any difference between the version on my laptop with OpenGL2 and the version on my desktop without it. Just grateful to have it working!

I just tried both mods and visually could not see any difference, I would say that it just has the option there for cards which don't support open GL, on some older cards GL might be faster than without.

maybe...

Two HD5850's in crossfire, it's quite a beast . The X800 must handle OpenGL differently to the 58** cards. Glad you sorted it anyhow

[Merlin999]

Thanks Earl_UK and Revs. I'm glad it's working without me having to splash out on a new graphics card!
