I remember, when XFree86 4.3.x finally appeared in sid, I had similar troubles. Tracked it down (at bugs.debian.org) to a version incompatibility with the GL libraries. I don't remember the details anymore, try to have look at bugs.debian.org > * Does anyone know if this machine is known by a different name? > linux-laptop.net doesn't list the model, although other sites claim > various Latitude models are actually PP01L.

Sounds much like my ( company provided) Latitude C640. I would not have bought it myself. The performance simply sucks, a kernel compile on a Duron/900 box with 512 MiB RAM was noticeably faster than on the notebook (P4M/1.8GHz, 1024 MiB RAM) Also, the display chip has some personality problems. SOmetimes, while changing video modes (start X, switch from X to terminal or back, resume after suspend), it decides to corrupt the display memory and all I can see is a chaos made of little coloured lines. The machine continues to run, I can see the mouse cursor (or text in terminal) changing. Pressing Fn-D does not help, it always comes back to the same garbled screen. Neither helps a suspend-to-ram and wake-up. In the worse case, the complete system freezes and the corners of the display start to slowly get whiter. To be fair, it does not happen when I use a VESA driver or in MS Windows. So it sounds more like a problem with the driver. Still, the net result is that it does not work as I would like it to. The DVD drive is no good as well, playing a dvd takes almost 100% CPU (both in Linux and Windows) and the output resembles a slide show. (Yes, I made sure that DMA is switched on for ther drive). As to power management, APM works better for me, the Fn-* shortcuts works. The did not work with APCI enabled in kernel, even though got more detailed info about the machine, like CPU temperature. I have not investigated it much. With the laptop-mode patch (included in 2.6.6), I get cca. 2:30h from the battery. I have no use for the modem, so I have not even tried to get it working.
