I just fixed the dodgy power inlet on flaptop. Soldering with a 15watt soldering iron was like using a heated sledge hammer but i persisted anyway and replaced the 19v power inlet with a permanant cable.

Unfortunatly i seemed to have damaged some of the onboard video :(

I can boot up, i can watch all the text as Mepis starts, but instead of eventually seeing the login screen i see a blank screen appear instead. I can boot and run live CDs, such as yopper, which will run happily at a low resolution. I can boot up MEPIS live, which runs at a higher resolution, but i get the same problem..

I figure what i have to do is either use a keyboard shortcut to lower the screen res, or boot up under another live distro, and edit something somewhere so its discustingly low res, but atleast within what my damaged machine can now run.

Clues please?

426872 2006-02-03 20:16:00 I haven't done anything like this for ages but..
can you not use the livecd (the one that works) to alter your xorg.conf?? file, and try copying the relevant refresh rate/resolution from the livecds conf file to the installed linuxes conf file

Try this first
have you tried making it boot to command line and then running your Xconfiguration thingie there (sorry my memory for isn't as good as it used to be)

sudo dpkg-reconfigure xserver-xorg

or

xconfigurator?

I could do that, but i'm hoping to know sort of exactly what i'm doing before i do it, hense this post.

It would seem the only option is to boot of a live cd and edit a configuration file, as you sugggest :groan:

426874 2006-02-03 20:58:00 Try this:

When you see LILO, hit the Tab key. Then enter in linux 3 which will boot Mepis to runlevel 3 (CLI only). Log in as root and navigate to /etc/X11/. Open up xorg.conf (think that is what Mepis uses) in a text editor such as Joe, Nano or Vi and edit the Screen Section so that a lower resolution is the default. Save and exit and then reboot the machine and see if this helps. :)

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24 <-- change this to perhaps 16
SubSection "Display"
Viewport 0 0
Depth 16
Modes "800x600" "640x480" <-- Check resolutions are OK
EndSubSection
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1280x1024" "1152x864" "1152x768" "1024x768"

Is there an equivelant command for getting to commandline under grub?

426877 2006-02-04 03:22:00 Is there an equivelant command for getting to commandline under grub?OK, so Mepis uses GRUB and not LILO ... :p

It is a little bit harder with GRUB, so why not just try this first. Let the machine boot up until you get the blank display where the GUI login manager should be. At that point, go CTRL-ALT-F1. All going well you will get a usable terminal to log in as root and you can go off and hack xorg.

If that doesn't work for some reason (it should) then you will need to log into your system in a single user mode from the GRUB menu. Have a read of this (www-128.ibm.com). The part you want is where you append the word single to the kernel line so that part looks like this:

root=LABEL=/ single

Really odd why your laptop now only displays at a lower resolution after your DIY of the power thingy. Nothing in the BIOS behind this?


Jen, you are a bit of a Linux geekWear the badge with pride, although I am just a junior Linux geek, so much still to learn. :D

426878 2006-02-04 03:42:00 OK.. i got passed that one.

Mepis will load as a live CD using the 2.4 minamal settings it refers to as safe mode...

From that i was able to edit out any suggestions that anything above 800x600 was possible.

I know have a very ugly, but working flaptop!

Thankyou! :D

Too right, Linux is so conifgurable, that, you really do have to study the OS just to know where it ends.

426880 2006-02-04 04:21:00 another way of getting to a cli

Once you have the black screen ( x's equivalant of bsod , but not so terminal) press ctrl alt and backspace keys, that will shut down x and give you a cli then you will be able to login to mepis.

I too had this problem and I used this method of getting to a cli to impose the live cd settings on a HD install.
