[SOLVED] Screen Resolution

trishul14 · 06-08-2011, 07:54 AM

Hi all,
I installed Zenwalk a couple of months ago.I had no problems until recently when the resolution of the computer suddenly changed.I tried changing the resolution first by going to startup>settings>display and the resolution options available were only 800x600 and 640x480.My monitor is 15 inch monitor.The screen looks real bad i tried finding the solution by following the procedure given in this thread http://www.linuxquestions.org/questi...lution-480062/ .Even this did not work properly

Later I did videoconfig by logging in as root.Even after that the resolution did not change

Please help me out in this regard.

With Regards,
S.Puneeth Kumar

What's the make and type of the monitor? Or better, point us to the specs.
Which video card are you using?
Any pointers in the X log files in /var/log? Lines starting with WW (warnings) and with EE (errors).
If you have a xorg.conf in /etc/X11, please post it (between [code] and [/code]).

Hi,
My monitor is HCM 510LSA 15 inch LCD.Since I am using only zenwalk i could not find out which grapic card i am using.My system is Intel Pentium 4.Initially the resolution was good.Power supply got cut off suddenly.I was not in the root user but.I was told that if we are in root user we'll experience such problems.But I was not logged in as root user
I have posted the entire xorg.conf(except the initial few lines) file here please bear with me.

The below modification in the monitor section might sort it out. Restart X or reboot your system after the modification.

Code:

Section "Monitor"
Identifier "Monitor1"

# HorizSync 31.5 - 50.0
HorizSync 30.0 - 60.0
# VertRefresh 40-90
VertRefresh 55-75
# Option "UseEdidFreqs" "1"
# Option "DPMS"
# Option "ReducedBlanking"

EndSection

To find the video card, use lspci and look for VGA and display

Also check out that your default depth (which is 24: DefaultDepth 24) is not commented out (which seems to be commented out in your case)
Remove # from:
# Subsection "Display"
# Depth 24
# Modes "2560x1600" "2048x1536" "1920x1440" "1920x1200" "1920x1080" "1680x1050" "1600x1200" "1600x1024" "1440x900" "1400x1050" "1400x900" "1360x768" "1280x1024" "1280x960" "1280x854" "1280x800" "1280x720" "1200x900" "1152x864" "1152x768" "1024x768" "1024x600" "854x480" "848x480" "800x600"
# EndSubsection
The above must be edited by hand as root.
Be very careful when changing sync values though. You may damage your monitor. You must first check ranges with manual/specification sheet.
Check results. If you do not have success revert back to original values (just in case).

It would be helpful to others to write what exactly worked so they can be assisted by reading your post...
Also you can mark the thread/problem as solved using the thread tools..
Best of luck to you...

Wim Sturkenboom · 06-09-2011, 02:29 AM

If it was 'my' solution that worked:

Now this works, you can also try to comment those new lines out (put a # in front of them) and and uncomment the UseEdidFreqs (remove the #) and see if that works.

What that will do is to allow the system to inquire the horizsync and verrefresh from the monitor itself. Advantage is that you will not run into problems when replacing the monitor by one with lower specs and when replacing with a newer one it will automatically pick it up and user higher resolutions.

Just check if it works; if not, you can fall back to the 'original' solution.

trishul14 · 06-10-2011, 10:07 AM

I implemented both the solutions at the same time!!So both of them worked I guess!!!Screen appears much better than before!!!
Sure I wil mark this as solved and I will also try the suggestions give n by Wim and get back!!

I am sorry but I have no idea or the knowledge to help or solve your problem as it never happened to me, but:
a) it would have helped you if you made a search for similar problems (I am sure you have already done this),
b) if you had not found anything similar in your search it would be a good idea to start a new thread. Posting in a thread marked already as solved minimizes chances for people with the knowledge to help you.
c) It is always a good policy to inform people of your distribution and xorg or other settings and be as precise as you can.

Best regards and good luck...
