I am trying to play Wolfenstein Enemy Territory and Urban Terror on a Thinkpad T400, however, both games have the same issue where the screen flashes(?) twice and then exit. The flashing(?) shows dark horizontal lines and a small black area in the center of the screen that is unaffected. I also cannot provide screen shots of it. Running the games in a terminal do not reveal any errors, however they both show "Recieved Signal 7..." on the terminal before they exit.
I have the latest drivers for my graphics card, and my computer supports up to openGL 2.1
I have a ATI Mobility Radeon HD 3450/3470 and a Mesa Mobile Intel GM45 Express Chipset gpu.
A quick google search shows no results for my current issue
Signal 7 (SIGBUS) is received by a program when it attempts to make an invalid use of memory.
This includes things like out of range memory, invalid array indexing and just flat out running out of memory.
My guess, since you said you're on a T400, is you have just run out of GPU memory when trying to run the game.
