I had this occupation a few days dorsum together with it took me one-time to figure out what to do.
I convey a NVIDIA GTX460 Graphics carte du jour on my electrical flow machine together with a Acer 22" Monitor. After installing NVIDIA driver, my display was stuck at 640x480 together with no affair what I do, zilch fixed it. This is an odd occupation amongst NVIDIA driver. I am assuming Intel together with ATI driver mightiness convey similar issues.
Fix Linux display issue
So if you lot are having occupation amongst your display or if your display is stuck at 640x480 therefore endeavour the following:
Edit /etc/X11/xorg.conf file
root@kali: # vi /etc/X11/xorg.conf
You volition run across something similar this
Section "Monitor"
# HorizSync source: edid, VertRefresh source: edid
Identifier "Monitor0"
VendorName "Unknown"
ModelName "Acer X223W"
HorizSync 28.0 - 33.0
VertRefresh 43.0 - 72.0
Option "DPMS"
EndSection
Now the lines that command display inward monitor is the next two:
HorizSync 28.0 - 33.0
VertRefresh 43.0 - 72.0
Depending on your monitor size, you lot convey to disclose the right HorizSync VertRefresh rates.
Find supported HorizSync VertRefresh rates inward Linux
This took me quite some fourth dimension to create upward one's heed precisely what I am looking for. I patently tried xrandr command similar anyone would do..
root@kali: # xrandr --query
This gave me an output similar the following
root@kali: # xrandr --query

HDMI-0 disconnected (normal left inverted right x axis y axis)
DVI-I-3 disconnected (normal left inverted right x axis y axis)
Bugger all, this doesn’t aid me to disclose supported HorizSync VertRefresh rates. I went around looking for options together with works life this tool that volition produce precisely what you lot demand to find.
Find monitor HorizSync VertRefresh rates amongst ddcprobe
First nosotros demand to install xresprobe which contains ddcprobe.
root@kali: # apt-get install xresprobe
Once xresprobe is installed, therefore nosotros tin run the next command to disclose all supported monitor HorizSync VertRefresh rates including supported Display Resolution … good the whole lot .. some fifty-fifty I wasn’t aware.
root@kali: # ddcprobe

Now the occupation I am interested is this:
monitorrange: 31-84, 56-77That’s the highest supported HorizSync VertRefresh rates for my monitor.
ddcprobe also gave me few to a greater extent than useful info, similar MonitorName together with Monitor Serial.
monitorserial: LAV0C0484010
monitorname: X223WNow fourth dimension to set it all together.
Edit xorg.conf file to amongst right HorizSync VertRefresh rates
So instantly nosotros know the exact values nosotros demand to know. We tin instantly edit our /etc/X11/xorg.conf file amongst the values nosotros want. So I’ve edited my xorg.conf file to expect similar the following:
root@kali: # vi /etc/X11/xorg.conf
And this is what you lot see:
Section "Monitor"
# HorizSync source: edid, VertRefresh source: edid

HorizSync 31.0 - 84.0

Save together with operate yesteryear away xorg.conf file, restart together with I am instantly enjoying 1680x1050 display on my Monitor. Here’s the xorg.conf file I convey right now:

This fixed my occupation quite well. It mightiness last useful to person else out there.
Reference Websites together with posts
The biggest aid is e'er X.org website for whatsoever display related issues.

I also afterwards realized the that Eddy posted a similar occupation inward 1 of my posts where he fixed this occupation likewise inward precisely similar way.
doh! I should’ve simply searched my ain posts together with readers comments. Eddy’s ship service doesn’t outline how to disclose the HorizSync VertRefresh rates though. Either way, Eddy’s ship service was the virtually accurate I works life related amongst my problem.
Here’s Eddy’s ship service together with my comments for references:
Thank you lot together with R due east southward P due east C T !
Eddy Ok Sorry Again
Now If person has my occupation amongst the resolution delight produce this !In /etc/X11/xorg.confHorizSync 28.0 – 33.0
VertRefresh 43.0 – 72.0and supercede them withHorizSync 30.0 – 83.0
VertRefresh 56.0 – 75.0That solved my occupation together with therefore it should for you lot every bit wellTHANK YOU AND RESPECTblackMORE Ops Post author Hi Eddy,
Are you lot on a flatpanel screen? This link seems promising .. http://askubuntu.com/questions/100900/how-do-i-set-the-correct-monitor-resolution-with-nvidia-drivers-for-a-monitor-th
