help with ubuntu display problem

[killkoy]

Ive just installed ubuntu using the alternate cd.

It boots fine using grub, but when it tries to load xserver (i think thats what it is ) I just get a load of coloured lines on the screen.

I have tried pressing ctrl alt f1 to access the teminal then using the following command line to configure xserver but it doesnt seem to have any effect.

sudo dpkg-reconfigure xserver-xorg

I have also posted a thread asking for help here

Any help would be much appreciated

Thanks, killkoy

I had a similar, and in the end got bored trying to fix it, but was told that trying to install without the fancy gui might help [never tried it, later that day vista beta got released]

[killkoy]

ok then, x now starts, by using vesa driver in

sudo dpkg-reconfigure xserver-xorg

now im having trouble connecting to my wireless network
i have a an edimax card that used ralink rt2500 and have been trying to use this guide to set it up: https://wiki.ubuntu.com/WifiDocs/Dri...t=%28rt2500%29

it is a wpapsk encrypted network. I have tried changing the network so that it is just wep encrypted but that doesnt have any effect.

When i type

sudo ifup ra0

after doing the process described in the guide i get lots(4/5/6) messages saying something like scanning port 67 for dhcpthing.
then a message saying no dhcp, or something like that.

Any help much appreciated

Thanks, killkoy

update, when i types udo ifup ra0 i get this:

the easiest way is within gnome - system/administration/network/wireless connection/properties

pick an essid, insert a key.

once you have a net connection, install the "network-manager-gnome" package, which is a considerably more sophisticated way of managing multiple network connections - in order to use it, you'll need to remove all wireless keys or lines starting with "auto" (except auto lo) from /etc/network/interfaces, then reboot. see https://wiki.ubuntu.com/WifiDocs/NetworkManager for more detail, and an example config file. note that network-manager-gnome will deal with WPA happily

on the topic of your geforce, was it set to use "nv" (open-source 2d driver) or "nvidia" (closed-source 3d driver)? to use the latter, assuming you want 3d, install the nvidia-glx package and run "sudo nvidia-glx-config enable". see https://wiki.ubuntu.com/BinaryDriverHowto/Nvidia for more detail

when i typed sudo dpkg-reconfigure xserver-xorg it was set to nv by default, there wasnt a nvidia option.

ok thanks, will give that a try

just checking. non-free software like nvidia's drivers shouldn't be enabled by default

ok i had a go at connecting to my network with just open encryption but it didnt work. it said that ra0 was active but the internet wasnt working and i couldnt ping the router.

You disabled all security on your network?

[killkoy]

yes i did(including wep), however i have just tried it using wep with a ascii key entry method instead of hex and it conected fine.
i have just downloaded network manager, however i cant see an option to enable wpa?, it just lists three different ways of implimenting wep

doesn't sound like the network manager screen. the network manager should just be a little icon in the system tray, which lists available networks when you click on it (and stores their keys). anything else is down to the gnome network configuration screens, which are something else

[killkoy]

yep thats what im talking about, i click on my network and then it only gives me conection options, the only types on encryption key things it allows me to use are wep ones, no option for wpa.

anything else is down to the gnome network configuration screens, which are something else

Are these the screens accesses by system/administration/network, or are there new ones i got when i installed network-manager-gnome, i installed the package by

sudo aptitude update
sudo aptitude install network-manager-gnome

was this the right way to do it?

[killkoy]

when i click on connect to a network i get

there are only 3 options in the drop doun menu:
wep with passphrase 128bit
wep hex 64/128bit
wep ascii 64/128bit

shouldn't i be getting something like:?

[directhex]

try setting "ENABLED=0" in /etc/default/wpasupplicant, then reboot. thsi ensures that control of WPA is given to networkmanager, rather than to WPA supplicant

[killkoy]

yes it is, i created that file when reading another guide on using wpa on the internet.
"ENABLED=0" is its only entry. Network-manager-gnome doesnt seem to conect to my network at all, even with encryption off. Only the original system/administration/network/wireless seems to allow me to conect.

[directhex]

odd, works for me :x
