My new Lenovo T500 has two graphics cards: an integrated Intel GM45 and an ATI Radeon 3650. Surely, with the myriad choices of card and driver, I could find one that gave me 3D performance, 2D compositing (true translucency), and good battery life, right? Wrong.
Here are my results after ~24h of futzing with drivers. The OS is Ubuntu Karmic. I believe the driver authors are all aware of the shortcomings, and all this garbage should be fixed someday. I didn't test out 3D acceleration, but you and I both know that ATI's better than Intel.
| ATI (Radeon) | ATI (Fglrx) | Intel | |
|---|---|---|---|
| Extra CPU interrupts / second | 0 | 60 :( | 0 |
| Watts used (over Intel) | 16 :( | 2 | 0 |
| Max battery life on a full charge (approx) | 2.3 hours :( | 5 hours | 7.5 hours |
| 3D Acceleration | Good | Good | Poor :( |
| 2D compositing (translucency) | Yes | Not with 3D :( | Yes |
I decided to run with the Intel card and drivers - if I really need to game, I'll install Windows on another partition and reboot.
As I was helping my grandpa move into his new apartment, buried
amongst the pink slacks and talking wristwatches was a tie clip. Like
a magpie, I swooped in and captured the shiny cylinder (the pater
familias gave me the OK, don't worry). But oh! It wasn't just a tie
clip - it was also an extensible pencil. The pencil telescopes from
2.25" to 4.13" and takes 1 mm lead. Twisting the tip advances the
lead. Of course, there's not much lead to advance.
