Hi all, i have Radeon Mobility FireGL 9000 (RV250 gpu chip) and use open source driver, after switching to KMS i have some artefacts on planets like this - http://gallery.icf.org.ru/icfteam/GHhos ... 7.png.html and http://gallery.icf.org.ru/icfteam/GHhos ... 0.png.html, and white square instead oolite logo while game startup, all other works fine, oolite version 1.76, is here any way to fix this? snips from logs:

Hi GHost, welcome to the boards! Unfortunately our local Brains Trust (of which I am not, I have to say, a member) seem to be drawing a blank on this one, but maybe a small *bump* might get something going ...

Like Disembodied, I'm no expert.
But since you mentioned that the start-up logo is blank, please try to start Oolite with the -nosplash option.

That would be oolite.exe -nosplash

It's a long shot, but worth a try while we wait for the experts to come along.

Minor correction: Gimi, the command line should probably be

Code: Select all

oolite -nosplash
There's no oolite.exe in linux! :)

GHost, it seems that your kms mesa driver is still leaving something to be desired.
I'd try and see if there are alternative (i.e. proprietary) drivers available for your chipset, and/or hopefully try and prod the mesa driver developers in the right direction. Failing that, I'm afraid that your only other option as far as Oolite is concerned is to revert from kms to a more mature - if somewhat slower - X driver.

Unfortunately Oolite can only work with what the OS tells it it can do.

I know that! I know that! (he tells himself) and I promise myself right now I will remember that next time.

Hi.

Seems you are right, i try switch to UMS and artefacts goes away, --nosplash not change anything, i also find there buffer and colors depth setup in code and try to raise limits but no luck, seems it broken comletely on any color depth, i add bugreport to mesa developers about this - https://bugs.freedesktop.org/show_bug.cgi?id=48203 , but according to numbers of bugs open seems its very long time to wait a fix:) there is no proprietary drivers for my hardware, and also i hate such blobs:)

Also i test latest svn trunk with NEW_PALENTS enabled and it's work fine without artefacts, but it's not very stable and i have no shaders.

GHost,

it seems your videocard uses the classic R200 driver, and that driver will not get many updates.
One thing you could try is switching to the latest stable mesa version, 8.0.2 . It has many improvements.
What distro are you using ?

right, it's r200, it's can work with classic and KSM depends from settings, with classic all fine, problem appears only with KMS mode. i use debian, there is no mesa8 in it for now, only in experimental and 8.0, not 8.0.2. in 8.0 i don't se anything related to r200 in release notes, i will try build in by hand a bit later, will see is it change anything.
