Title: 13db9cf: black/blank screen when starting, game freezes
Post by: tomreyn on 6 July 2012, 15:43:30

After deleting my old 'build' directory, I built a fesh copy of 13db9cf today, renamed all my .ini files to *.orig and ran it. Unfortunately I did not get very far: I ended up with a black screen right after starting it up, and a frozen game which would not react to anything (tried Enter, Alt-Enter, Alt-F4, kill -1) but kill -9. It did write a gae-crash.txt file, though:

=======================

I'm on (K)Ubuntu 12.04, using the default (open source) r300 (radeon) graphics drivers. More hardware details about this 'atibox' can be found in my forum signature below.

Looks like libtxc_dxtn crashes. Not sure how we trigger that. Try disabling texture compression with the following option in ~/.glestadv/glestadv.ini:

Code: [Select]

RenderCompressTextures=false
Add it if it's not there already.

I think they changed something in newer mesa versions (8.x) which breaks it for us. It worked for me before but doesn't anymore. I have a closer look this weekend.

Hmm, adding RenderCompressTextures=false doesn't seem to have helped much, the behaviour is, as far as I can tell, the same. Here's the latest crash log with a full rebuild of 0.3-994-g13db9cf:

Just for referecne, I had previously discussed a similar or possibly the same issue (https://forum.megaglest.org/index.php?topic=7932.0).
