"true" it actually suggested, but i havn't spotted any troubles with "false" - might be chiprevision thing. if it works, you'll get better acceleration (XFree 4.3). see XFree86.0.log if it's turned on on your box. i also disable most of lines in the modules section. exept "extmod". > > * Not out of the woods yet, or what fits in 64MB? > [...] > > 1) fluxbox - Fluxbox window manager > > I also had good experiences with Window Maker.

Fortunately, so far I never had > reason to do so. it's a good idea to roll your own kernel. you can omit lot of the stuff and the kernel will become quite small. it's quite a problem as the 2.6 kernels are bigger than 2.4. however 2.6 provides better acpi support (IMHO) and that's a good thing on notebooks. the CFQ shcheduler is somewhat smaller than the default AS. might give you better performance. deadline is also there, but this one is IMHO better at working databases. question: has anybody a working thermal sensor on the lib? i get a value at bootup which looks valid, but it doesn't change then. even unloading and then modprobe thermal doesn't reread it. if it boots up cold it say's about 20 degrees. if boot up hot, 50-60 degrees seems quite possible rihgt. i don't even know if there _is_ a thermal sensor in there. i compile on a faster local machine which is also the server for bigger remote apps like audacity, openoffiice, firefox, gimp,... > [...] > > 3) Enhanced Port Replicator.
