monitor type detect difficulty


Hi mates!

in fedora 8, i can change my monitor type setting by going to System-administration-display and choose the tab "hardware" then clicked configure. the computer recognizes my monitor by default as CRT and i can only get a resolution of 800x600 at maximum. by changing this monitor type into LCD I have more resolution option.

however, in other Linux Distribution such as Fedora 10, Ubuntu, i cannot configure the monitor type by GUI like above anymore so i guess i stuck with CRT configuration with max resolution of 800x600.

can anyone help me to solve this problem. I want to change the monitor type setting into LCD where I can get higher resolution.

What kind of monitor do you have CRT or LCD ?
What is the content of you're xconfig ?
It does not make sense for me that the resolution change with monitor type LCD or CRT .
Because I buy myself a new LCD monitor and yes it says monitor type unknown but I get still the correct resolution.

What is your video card type? If you do not have drivers for your video card as part of the OS (nVidia, Ati) you could be stuck with low resolution.

it doesnt make sense for me also

my monitor is LCD.
as I have mentioned above. if I dont change the monitor type from CRT to LCD (I can only do this through GUI application in fedora 8), i can only choose 1 resolution which is freaking low. I dont know how to change the monitor type in ubuntu or newer version of fedora because there is no GUI apps for that.






by the way, this is my xorg after i change the monitor type if u r interested in. i dont think it is really imporant.
in ubuntu, i have tried thousands times to change the xorg to get higher resolution but all i can get is the spooky 800x600 before installing nvidia driver and even more spooky 640x4"xx"

the problem must be about monitor type detection.

If you like to do it using the GUI in UBUNTU 9.10 system>Administration>System Testing
You get a lot of option skip one by one until you come by the monitor .

In UBUNTU 9.04 system>Administration Display Preference .
My Fedora is down now so I can not find it for you.

thanks mate!
but in Ubuntu 9.04, i cannot find System-Administration Display Preference. the option Display only gives me resolution of 800x600 at maximum, the monitor type is not recognized as LCD as in fedora 8.

blacknumber,

Usually this happens when the system does not have the correct driver for the video card. Get the right specification for the card, do this:

blacknum@host-$ lspci <Enter>

an output will include somewhere at the top the name and version of your card. Then you can hunt for the right driver it needs, and you install.

Another way is more simple: In my Ubuntu days there was an applet called 'eNvy' which can be launched from the Menu, try to find if your version still has it. Get on line, click Menu > Accessory > System > eNvy, then this applet will work in the background, it uses the internet to find the fitting Linux driver for your card, downloads and installs it automatically. That's one nice thing of Ubuntu I had before. If eNvy doesn't install for some reasons it will inform you that download is done. You only need to cd into the directory of the downloaded file and launch the driver script this way-

blacknum@host-$ chmod 755 ./downloaded-drivEr.ver.xxxx.sh <Enter>
blacknum@host-$ ./downloaded-drivEr.ver.xxxx.sh <Enter>

don't ignore the dot+/, be sure put it before the name of the driver. If driver needs to recompile a kernel it prompts you, just click Yes, when done you will only need to restart X then you shall have many choices of resolutions for the screen.

If eNvy is not available or doesn't apply in your case because the card is an intel, you can manually hunt the driver at www.intel.com and do the same installation procedure above.

Hope this helps.

Good luck.

thanks Mate!!!

actually in UBUNTU, I have tried Envy, compiled source code from NVIDIA site (my card is NVIDIA ), installed by the default "restricted driver", they all successfully installed but all i got is a freaking low resolution 640x480 eventhough the desktop effect runs fine (i use 173.xxx driver for my FX 5300 nvidia). the resolution option in GUI only show 640x480 and lower.

I am dam sure that the problem is about the monitor recognition as I have told in the very first post.

if I'm wrong in this case, u can cut off my head mates!

why i am that dam sure, because in fedora 8 and only in fedora 8 and the prior versions of fedora, i can find the GUI application for changing the monitor setting from the freaking CRT to LCD (i have mentioned the the in earlier posts how) where i can select higher resolution. in this fedora 8, the driver 173.xxx works perfectly for me with my desired screen resolution.

What about manually editing (backup first) your /etc/X11/xorg.conf file with values from Fedora 8? That should work.

And check if /etc/X11/xorg.conf has lines that you were obligated to add (or installation script) for nVidia driver to be recognized.

This is boggling the mind. Nvidia under my Ubuntu had a configuration GUI application, there you can reconfigure anything, there the correct monitor is automatically synced.
Try look for a newer Nvidia Linux driver, download and run (usually you don't need to compile it) I remember it was a script with a ***.run extension.
These days it is only very rare to find a "monitor spec" that drivers cannot handle. If this is your case then it needs more work therefore.

Good luck.

hi mate!
the GUI for configuring display in fedora 8 has a manually tool under the "hardware" tab for me to change the recognition of my monitor. i found out that it detects my monitor as CRT by default while my monitor is LCD.
however, in ubuntu, that GUI application doesnt have the tool for manually detect the monitor. the automatic figure fail to detect it (it says unknown screen). i guess my problem falls into the second case

is there anyway i can manually detect my screen type and set the resolution. if yes then please tell me step by step because i am very newbiely

thanks for ur effort to help anyway

Look at google hits I prepared for you: http://www.google.com/search?q=xorg+...ient=firefox-a and see if anything fits. "[ubuntu-my] How to configure my monitor and display adapter in ..." might be the best one.
