New monitor shows no graphics at login

Asked by jetandein

I installed Ubuntu 8.04 off of a disk a couple months ago and have been trying to figure out how to use it. I just bought a "Maxent MX-26X3" which is a tv but it had computer inputs also so I decided to use it on my computer. I unplugged my old monitor and plugged this one in and everything seemed fine. After grub loaded it did the usual Ubuntu logo with loading bar but when it got to the login screen the display went black and it says something like "invalid input"

 My computer dual-boots to windows xp and everything works fine there. I've searched for an answer but am fairly computer illiterate. I tried going into recovery and typed

 sudo dpkg-reconfigure xserver-xorg

and all that did was ask about my keyboard and never asked about my video or monitor.

I tryed pushing ctrl alt with + or - or backspace at the login screen and still got no display.

I tryed
sudo displayconfig-gtk
and it said: (gksu:5554): gtk-Warning **: cannot open display

also just so you know, the ubuntu boot disk works and displays stuff fine when running off the cd

Any help would be awesome

Also would just reinstalling ubuntu possibly fix the problem?

In the recovery option try deleting (or renaming) your old xorg.conf file

mv /etc/X11/xorg.conf /etc/X11/xorg.conf.bkp

then restarting.

I'm not sure how to delete or rename it.... Sorry as I said before I am very new to linux and am computer illiterate... if you tell me what to type I can probably do that... I just turned my comp on waited till it got to the login screen and hit ctrl alt f2 and logged in and typed:
mv /etc/X11/xorg.conf /etc/X11/xorg.conf.bkp
and it told me mv: missing destination file operand after `/etc/X11/xorg.conf.bkp'
 thanks

Errr, it needed a sudo at the front to give the command SuperUser priveleges. I'm not sure that this is a good move to make tho, but here goes

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

then it'll ask for your normal user password, not your Sueruser/Root one

Good luck and regards from
Tom :)

well if it's not a good move to make then should I do it? Also still curious if reinstalling ubuntu would be a quick fix?

You've got a backup for if it doesn't work - you can simply copy your backup file back.

X.org auto detection has become significantly better in recent times.

Ok so I waited till it got to the login screen and hit ctrl alt f2 and logged in and typed:
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.bkp
It asked for my password and I hit enter and then it gave me a promt so I typed:
Sudo reboot
and my screen went black when it got to the loggin screen.
I hit ctrl alt f2 logged in and typed:
sudo dpkg-reconfigure xserver-xorg
answered all the keyboard questions again and after the last keyboard question it said:
md55sum: /etc/X11/xorg.conf: No such file or directory
and then it gave me a prompt so I typed:
sudo reboot and booted into window so I could type this... any suggestions...?

Can you post the contents of /var/log/Xorg.0.log ?
(It's quite long, so you could use a site like pastebin.com, but if that's not possible just post it up here)

What cable are you using to connect the monitor (DVI / analog)?

You can type

sudo touch /etc/X11/xorg.cong

before

sudo dpkg-reconfigure xorg-xserver

to ensure that you have a xorg.conf file for reconfiguration.

Honestly I don't know how to post the contents of /var/log/Xorg.0.log or even how to see them... I still have the old monitor though would that help with any of this... also is there a driver for my video card... I think it's a ATI Radeon 9200SE... How would I go about downloading it and installing it and would that even help my situation?

The tv you have supports a max resolution of 1280x1024 (http://homepage.mac.com/jedimstr_/blogwavestudio/LH20050423151819/LHA20050714111211/index.html). It seems as though the computer is rying toput the monitor into a resolution it cannot handle - possibly the resolution you used previously on your old monitor. LCD tv's are nice for their size, but often their resolutions aren't as high as a monitor.

can you post the output from running the following command in the terminal

xrandr

That gives you the list of resolutions supported by your monitor.

I typed:
xrandr
and it said: Can't open display
I also tried:
xrandr -q
and
xrandr --verbose
and they both gave the same: Can't open display

I am sorry if I am doing it wrong as I have said I don't know anything about linux.

Sorry, my mistake, xrandr won't run from the outside of an x session on my computer either.

X configuration may work better if x.org isn't running.

Try this:

boot up, and when he screen goes blank hit Alt-CTRL-F2 to jump to the command line.

Stop X.org with

sudo /etc/init.d/gdm stop

then reconfigure with

 sudo dpkg-reconfigure xserver-xorg

Then restart the login screen with

sudo /etc/init.d/gdm start

Hopefully it will then show the login screen! Let us know how it goes.

So I typed:
sudo /etc/init.d/gdm stop
and then typed:
sudo dpkg-reconfigure xserver-xorg
it had me configure keyboard stuff and then it said:
xserver-xorg postinst warning: overwriting Possibly-customised configuation file; backup in /etc/X11/xorg.conf.20090411223145
I then typed:
sudo /etc/init.d/gdm start
it said:
Starting GNOME Display Manager
and as usual my screen goes blank and the monitor says:
DVI No Support

P.S. I did some research on the tv and according to: http://www.thenerds.net/MAXENT.Maxent_26_LCD_TV_26_NTSC_181_Channels_169_1366_x_768.MX26X3.html?affid=8&ci_src=14110944&ci_sku=MX26X3^~^MAXENT
the Maximum Resolution is 1366 x 768 which is what I'm using right now in Windows XP.

Do you have a way of copying files from your Linux partition into Windows so you can paste them up here?
Try one of these :

  http://www.howtoforge.com/access-linux-partitions-from-windows

I'd recommend either of the first two to begin with. Once you've got that running can you post the contents of the file "/etc/X11/xorg.conf" here, so we can take a look?

You can also try looking in the file /var/log/X11.0.log, when you're at the Linux command prompt type

  less /var/log/Xorg.0.log

you can use the cursor keys for going up and down (press "q" to quit). Most of this is just logging information, but you may see something which gives a clue - anything on a line which starts with (EE) or (WW) is probably interesting.

Well I opened: /etc/X11/xorg.conf with notepad and this is what was inside:

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg

I'm a bit stumped with this. You could try adding the line :

Driver "vesa"

into the "Device" section after the line 'Identifier "Configured Video Device"',
this will force X to use a 'lowest common denominator' driver, but might at least get a login from where we can try and figure things out.
You could also try the new "Jaunty" release candidate CD. ATI has a new open source driver which may give you more luck.
If you want to wait for the final "Jaunty" release, it's due out next Friday.
