I'm running Ubuntu 12.04 on an old laptop, I've installed sdl, sdl_image, sdl_mixer, timidity, libpng, libsmpeg, etc. The scripts that come with the installation work - but only in console mode. The error log shows this:

Timestamp   : 24-3-13 03:02:43
Error level : FATAL EXCEPTION
Message     : Fatal exception encountered

I don't normally use Linux, so it's entirely possible that I'm doing something wrong.

Check out this thread. Hopefully that's the solution you need.

I don't think this is the same issue. I don't see anything, it crashes before displaying the title screen. The music plays perfectly in console mode, but I've been disabling the sound engine in config just in case anyway.

I'm not sure if this is related - If I run DoomRL from its directory in a terminal, it works. However, setting the config file option to console and clicking the DoomRL executable does not work.

When trying to run it in graphical mode, this is the log.txt output. (The error.log is the same as before.)

[Kornel Kisielewicz]

Exactly how "old" is the laptop? Screen resolution? GFX card? Graphics drivers?

[Zero Gravitas]

It's...pretty bad.

Screen resolution is 1024 x 768.
mobile AMD Athlon(tm) XP 1800+
S3 Inc. VT8375 [ProSavage8 KM266/KL266] (Jesus.)
As for drivers, the xserver-xorg-video-savage/S3 Virge packages are installed.

Are there minimum system requirements for the graphical mode?


Addendum: Save files that are created seem to be corrupt as well:

<TDoom//0> Save file corrupted! Error while loading : Access violation

[Zero Gravitas]

Okay, it looks like the save file thing was just a one-off, I can't repeat it. Save games are working correctly.

And I believe I have found the issue - software rendering. Apparently, the card's drivers aren't being used because the libgl1-mesa-dri package decided to drop the files I require for this card in the latest versions. Wonderful.

I hate Linux.

Addendum: Now I don't know what it could be. After much fumbling, I installed the correct drivers, added my account to the video group and (apparently) have got the card working with the correct driver. DoomRL still does not work past checking the resolution. Any ideas?
