Question 1:

Hi, can anyone help-me with that? I don`t know how to solve that i already search for solution in google and other places but without success /: I really need to use my laptop on 1280x800 i`m really tired of use 1024x768.

Question 2:

After i update my kernel to 2.6 i cannot use resolution like 1024x768 on shell. Why? How can i solve that? When i use the default kernel from slackware i only need to change in lilo.conf, now when i do that i have a black screen.

A1: add a new resolution 1280x800 to your /etc/X11/xorg.conf (or if you use XFree86, use XF86config or something instead of xorg.conf). Edit the file as root,
or use your favourite editor instead of vim. Locate the resolution lines (one line per colour depth), and where it says something like
add "1280x800" in front of it, so it becomes
do the same for every resolution line if you want that for every colour depth. Save, close and restart X (CTRL+ALT+BACKSCAPE while using X).

A2: maybe it's a kernel option. I haven't ever used that big resolutions in console, nor 2.4 kernels for a while. Search the web for how you use the 'vga=' option in the kernel line, if I'm right it's got something to do with this.

was that really necessary?
