I’m not sure why SLIM isn’t the default login in manager for LXDE, and I’m also not sure why I’ve never installed it before. But I just did, and I’m pretty pleased with the results. Just run
aptitude install slim
and when asked to select a default login manager choose SLIM. Then reboot, and run
aptitude remove gdm
Then use Synaptic to remove the residual config files. I’ve been using SLIM for all of 10 minutes, and it already seems much faster than GDM. To change the default theme, download (or create) a new theme, and place it in
and modify the slim configuration file
to select to the new theme. I couldn’t find an LXDE theme (I didn’t look very hard either), but I did find a pretty slick Debian one. Does anyone know why the LXDE project is developing their own login manager? This one seems pretty light weight and configurable.
