customizing ls time output

ls -l --time-style="+%d-%m-%Y %H:%M:%S" /var/log/xxxxxxx

It's the same syntax used by date command

Monitoring keyboard and mouse events

For some unknown reason the key combination ctrl+alt+f1 through f6 are not working, as well as ctrl+alt+backspace.

I'm still working on that but for now I have found some interesting ways to capture keyboard and mouse events:

For keyboard and mouse you can use a small app called xev. After installed just call xev from a terminal, a new blank window will pop up where you can test you mouse and the pressed keys will show up on the terminal.

If you have a touchpad synclient -m 1 can be useful to you.

I'm going to come back here to finish this post as soon as I figure out what's wrong with those key combinations.

Frame buffer modes

I'm always wondering my options for the "vga" setting at the grub command line. Here is:

Color depth      | 640x480  800x600  1024x768 1280x1024
-----------------+-------------------------------------
256        (8bit)|  769      771       773      775
32000     (15bit)|  784      787       790      793
65000     (16bit)|  785      788       791      794
16.7 Mill.(24bit)|  786      789       792      795

The vga= setting only effects the frame buffer, not X (unless you're using the fbdev driver in X). This'll mean that your console will display at this resolution.
