[ubuntu] Change config on screen

[TechSupp]

Got a Fog server running on Ubuntu but the HD is a little small so I thought I would image the PC on to another better one I have with a larger HD, anyway, imaged OK, but of course it did not like the graphics, so offered me chance of low graphics, thought that would do for the moment, rebooted now monitor complains that signal frequency is out of range! and can't see anything. How do I get in to change the graphics settings before I get to the point I'm at now. Sure if I took it in to work with me it would work OK in another monitor as had this problem before with windows but I'm at home not at work and no other spare monitor!

download a tool called webmin, this allows you to configure linux from a remote machine via a web browser

I don't like webmin, you could try:

 

For now, log in via the console and do the following.

 

sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.broken

 

sudo /etc/init.d/gdm restart

 

This will move the previous config file to another file so when X is restarted it'll automagically detect if it can.

 

What card is in there now? Output of lspci will do if you don't know.

Thanks, I'll remember that for next time...however it was a bit of a What a Plonker Rodney moment really..I do have another monitor to use...you've guessed it...the one I am looking at now attached to my own PC!!! (in any event more painless changing hardware with Linux than it would have been with windows!)

All's fixed now and its back on its own PC. The PC is actually a cachepilot which has two network ports, can I use both for FOG to improve speed of imaging? I know I should have posted another messing in the Fog part of the forum but thought I'd ask.

[kmount]

It'd probably be better for you to see if your network environment supports multicast than teaming the nics but yep you could do.

 

(I've not used FOG properly before so not sure of how it would play, definitely worth a post over in the forum there)

[TechSupp]

Because this PC will move around with me (I cover 4 schools) any imaging will be done on a small independant network to the school one (its only really used for when new batches of PC's arrive) so it will be Fog -> Switch -> client PC's

 

Now the next question, how do I find out the SU password or reset it! been a while since I used it!

[kmount]

Urm, if its ubuntu by default it won't have a known root password to directly su with.

 

Does su root (insert your password) work?

 

If so you could then passwd root and set one but to be honest, its fine left alone.

 

If the machines will be attached to a switch you carry around with you, if its a decent switch all should be well, if you're plugging this cachepilot into existing infrastructure it will be a bit more tricky, but then, teaming the cards into an unknown infrastructure could be a pain too.

[TechSupp]

password sorted on a last gasp trawl of my brain for what it could be :-)

 

Should be a decent switch when I get hold of it, last time I used just a bog standard D-LINK 8 port switch and the performance was not brilliant for just a couple of PC's at a time, hence the switch to the CachePilot. At least its all up and running now, Thanks

[kmount]

Not a problem fella.
