Boot options

[leventguner]

Hi,

I saw that in x11 conf file my display is shown as generic vesa display. I once tried to install the Parhelia driver but after the installation gnome screen was garbled (after boot up). I reinstalled the system.

I would like to try a different driver but I would like to be able to fix the issue this time. Is there a way to stop the boot process before gnome loads, it is initlevel I guess?, but how do I edit the file if I cannot boot up (ends in garbled screen.)

Then how do I uninstall the driver for generic one or another one? I have read that there is a kernel module and a gnome driver.. what is the difference?

Thank you.

hi

edit your /etc/inittab file and change default runlevel to 5

# The default runlevel.
id:5:initdefault:

and delete the S99gdm file from /etc/rc2.d directory

now , when you boot up write a "2" after the kernel name in the boot loader prompt , i think you use grub ,and unfortunatelly i don't know grub , i think you need use the grubs console but i'm not sure.

if you installed the driver from source you can uninstall it with "make uninstall" command , but if you installed it from package use apt for remove

Yeah, when the GRUB menu first appears, look below the menu for commands to edit the different menu lines. Highlight the line you want to edit before it boots:

e for edit a line
b for boot

Add the runlevel you want to boot into (as suggested above) to the kernel line.

I use lilo for booting. How do I get a shell before gnome to edit the inittab? The driver uses a run file to install.

Try going to the LILO prompt and pressing the TAB key before the system begins to boot, and then enter the word "single" on the end of the kernel command line.

If that doesn't work, try pressing Ctrl-x to exit the graphical screen and go to the boot prompt, and then enter:

linux single

Once the system boots, you should be able to use nano, vim, or some other text editor to edit your configuration files.

Hi

when you highlitgh a line in tyhe lilo menu its appear in the prompt behind the menu , just prees a space and write the boot options there.

Hi,

I installed the new driver but now I can't get the login screen just some garbled graphic(my old background I guess).

I can get the shell by Linux single, I tried to dpkg-reconfigure xserver-xorg for vesa driver but that didn't solve it, I had kept the old xorg.conf and replaced it with the new one, still no login screen..

What should I do now? reinstall gnome??

[leventguner]

I messed with dpkg-reconfigure xserver-xorg more and selected mtx and no kernel buffer and now it works...

The thing I don't like is I am not sure how I fixed the problem Now I would like to use refresh rates over 85hz which gnome doesn't let me select on any resolution. Which file should I edit to select the start up frequency?

How do I know which drivers X is using currently?

Thank you.

check the xorg.conf file

to incrase the refresh rate you need edit xorg.conf

in the monitor section , you can find a VertRefresh option , just incrase the maximum number.
for example

Section "Monitor"
    Identifier  "philips 107e"
    HorizSync   31.5 - 64.3
    VertRefresh 50-90
EndSection

leventguner, be sure to check your monitor manual and use the horiz/vert refresh rates suggested by the manufacturer, or you could damage your monitor if you use the wrong rates.

Let us know how it goes.
