what make&model is your graphics card? are you using the restricted drivers? could you also post the output of these two commands:


xrandr -q
sudo lshw -C video

[wolfen69]

try

sudo dpkg-reconfigure -phigh xserver-xorgthen ctrl-alt-bksp

[aagavin]

thanks for you help but none of the stuff I tried worked:



xrandr -q
output:

Did you enable your graphic card in System > Administration > Hardware Drivers?

Did you enable your graphic card in System > Administration > Hardware Drivers?

yea tried that and it said


No Proprietary drivers are in use on this system

[chriswyatt]

Used to have that graphics card, must be more than a decade old by now.

A quick search on Google pulled up this:
http://forum.freespire.org/showthread.php?t=5205

By the sounds of it it's not well supported on Linux. If all else fails you might be able to get a second hand or budget graphics card that's better supported under Linux.

[Ryadt]

yea tried that and it said

Try
sudo apt-get install xorg-driver-fglrx
and then retry to enable the driver.

[tangibleorange]

you might need to install the restricted driver using Envy-NG. Install it with this command:


sudo apt-get install envyng-gtk

Then launch it and follow the instructions.

Can you show me the contents of the following file:
/etc/X11/xorg.conf
on your system please.

also, tell me the exact name of your monitor, and if possible show me it's full specification.

[aagavin]

k thanks for your help

I will try it tomorrow because I don't have internet on that computer

will report back to you

You want a 1024x768 res, right?
where it says

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
EndSection

Under where it says Device "Configured Video Device", put
DefaultDepth 24

create another section below it (below the line of text that says EndSection), putting the following information:

SubSection "Display"
Viewport 0 0
Depth 24
Modes "1024x768"
EndSubSection




So that instead of


Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
EndSection
you have:


Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
DefaultDepth 24
EndSection

SubSection "Display"
Viewport 0 0
Depth 24
Modes "1024x768"
EndSubSection


Then restart X and tell me what you get
(to restart X, press "ctrl-alt-backspace")

it says that I can't edit it because I am not root
how do i solve this

[NightCrawler03X]

yes, to edit /etc/X11/xorg.conf, you need admin rights. If you're running ubuntu, your "root" password should be the same as the password for your user login.

At the terminal, do

sudo gedit /etc/X11/xorg.conf
(I'm assuming you use gedit as a text editor; if you use some other editor, just replace "gedit" with the name of whatever editor you use).

nope didn't work

when I restarted it just went into low graphs mode and i had to reconfiger it 800x600

[NightCrawler03X]

Hmm, then I don't know how to help, sorry. Come to think of it, your xorg config does look kind of bare-bones. Maybe, Ubuntu doesn't use xorg conf for everything (I wouldn't know, because I don't use ubuntu, I use ArchLinux (http://archlinux.org)).

I've got one more thing for you to try:
find out what video driver you are using, and do the following to your xorg config (while keeping the same things in there that I told you to put in there in my thread 2 previous to this one):

in the "Device" section, put


Driver "name_of_your_video_driver"

then restart X and see if that helpsand see if that helps.


PS: When you said you "restarted" do you mean that you rebooted your entire system? If so, I only meant that you should restart Xorg (or "X").

[nisaky]

Do you have drivers for your graphics card? Without proper drivers graphics cards don't work as they should.

By the way which one do you have?

[NightCrawler03X]

quoted from nisaky's sig:

There are 10 types of people on this world. Those who understand binary and those who don't.

0 1 10 11 100 101 110 111 1000 1001 1010 1011 1100 1101 1110 1111 10000 10001 10010 10011 10100 10101 10110 10111 11000 11001 11010 11011 11100 11101 11110 11111 100000 100001 100010 100011 100100 100101 100110 100111 101000 101001 101010 101011 101100 101101 101110 101111 110000 110001 110010 110011 110100 110101 110110 110111 111000 111001 111010 111011 111100 111101 111110 111111 1000000 1000001 1000010 1000011 1000100 1000101 1000110 1000111 1001000 1001001 1001010 1001011 1001100 1001101 1001110 1001111 1010000 1010001 1010010 1010011 1010100 1010101 1010110 1010111 1011000 1011001 1011010 1011011 1011100 1011101 1011110 1011111
the statement I quoted does not compute! does not compute!
*head explodes*

I don't mean to hijack this thread, but isn't this statement slightly incorrect? I mean, 0 basically means no, and 1 basically means yes. 10 in binary is 2, which means you are adding a third value (because there's 0 and 1 also).

0 - doesn't understand.
1 - understands.

So actually, there are 1 types of people in this world.

?? how do i restart only xorg

dont know how do i find out

[NightCrawler03X]

I already explained, but ohwell, I will explain it again:
look at your keyboard. Find the following keys:
ctrl
alt
backspace (should look something like a <---)
Press, ctrl, alt, and backspace all at the same time, to restart Xorg.


As for finding out what video card driver you have, try:
lsmod | grep drm
and tell me what it says.

also try
lsmod | grep video
and tell me what it says

and finally, do
lspci | grep VGA
and tell me what it says (keep note that you should do the "VGA" in all caps).

Hi

Go to terminal (applications - accessories - terminal) and enter:

sudo displayconfig-gtk

Then enter your password (wont appear)

Then in the gui which appears, select your model of monitor (or "Generic" if its not there), and set the screen resolution. This normally works.

[aagavin]

ok tried that but it still didn't work

because when i restart it goes into low graphics mode

[prap19]

I hav don all the things mentioned above sice i had the same problem.But now my screen doesnt appear and only black screen comes .What to do now???Plz its urgent i hav all my document in UBUNTU.

Since 10 binary = 2 decimally, then there are 2 types of people.

Sorry for interrupting in thread...



BTW Ubuntu "doesn't like" ATI cards much, there are no drivers for some so Ubuntu can't detect them at all.

in most cases running an xfix solves the resolution problem. Read more here: http://www.kshoster.net/?c=tipsandtricks&h=xfix

Hi,

Try:

sudo displayconfig-gtk

enter your password (will not appear)

Then change the settings in the GUI that appears. You may have to log out then in again.

Make sure you have the correct video drivers installed for your ATI 3D Rage Pro. Chances are, right now you're using the open source drivers; on my system I have an ATI Radeon X600 and I use the open source drivers, but I can get the full resolution and refresh rate that my monitor supports (1280x1024 @ 75Hz) -- in the past, I couldn't get the resolution I wanted with the open source drivers, so I had to use ATI's official drivers -- the same may be true for you right now.

Try using the proprietary ATI driver for your card and see if you can then get your desired resolution (if you're on ubuntu, in the program menu you will find in system > administration, something called either something like "Hardware Drivers" or "Restricted Drivers". If you go there, it'll probably tell you the correct driver to use, and from there you just enable it, then let ubuntu install and configure it for you (after doing so, you will need to restart your kernel (just restart ubuntu)). **

**Just keep in mind: the proprietary drivers may offer better performance in many areas, but being closed-source, only ATI can maintain them, therefore ubuntu folks and all other linux folks out there can't fix any bugs/security-holes in those drivers.

[johntc23]

using all the suggestions on this thread I finally have my screen resolution where I wanted it BIG Thanks:lolflag:
Ubuntu is great

I'm having the same resolution problem in Xubuntu (maximun allowed being 800x600 instead of 1024x768 ) but I haven't been able to solve it with all the above instructions. My graphics card is an S3 Graphics SuperSavage/IXC 1179 (it's a pentium IV laptop, 1.7GHz 256RAM), but I've only found the driver for windows. With the command sudo displayconfig-gtk, I can only select a generic s3 savage driver, and when I hit 'test', this is what the terminal shows:

on_button_test_config_clicked()
Traceback (most recent call last):
