low resolution [SOLVED]

bugreprt · Post by **bugreprt** » Sat Sep 18, 2021 12:37 am

Hi all. I've just done a fresh install of Cinnamon 20.2 64bit on a Dell Optiplex 9020 (20 gig of ram) with a HP Compaq LE2202x monitor. The monitor is 1920x1080 native resolution but the highest resolution available in display settings is 1024x768. The same hardware works fine with Windows 10. I've done many installations of LM Cinnamon and this is the first time I've come across this problem and I haven't a clue where to start to fix it. Please help.

Please post the results of

using </> button ( fifth from left just above this message window via copying them and pasting them so we have a better idea of what's under the hood and it will save on much speculation.

It will also tell us what drivers are being recognized and possibly loaded and help us begin narrowing down the culprit

My first guess is a driver issue. But without more details, it's simply a guess. SMG, if I recall correctly on here, has helped many with very coherent issues in the past. She's pretty fast and sharp on here, but I don't recall if it's a day shifter or not. She isn't the only one though that can help narrow down the problem.

Regardless, the bigger and more experienced brains here will probably need that inxi -Fxxxrz info.

I've mucked around with xrandr and got some more resolutions but after a restart they're gone. I think I can save them in a xorg.conf file but don't know how or where?

Usually, those settings are added to the bottom of your ~/home/.profile file.

Selected "Show Hidden Files" in File Manager. Double-click your ~/home/.profile file and it should open in xed (basic text editor on Mint). Add your new resolution lines at the bottom of the file and save the file.

Thanks SMG. Adding the xrandr to the .profile file worked okay up to 1560x1050 but not with 1920x1080. With 1920x1080 I get these errors:

screen 0: 1920x1080 508x285 mm 95.94dpi
crtc 0: 1920x1080_60VGA 59.96 +0+0 "VGA-1"
xrandr: Configure crtc 0 failed
crtc 0: disable
crtc 1: disable
crtc 2: disable
screen 0: revert
crtc 0: revert
crtc 1: revert
crtc 2: revert

Maybe the monitor is faulty though it works okay with Windows 10?!

With the monitor attached, what is the output of xrandr --verbose? Click </> from the mini toolbar above the textbox where you type your reply and then place your cursor between the code markers and paste the results of the command between the code markers [code]Results[/code] because the results will be long.

New development. I connected the monitor to a different LM computer using HDMI and it worked perfectly right up to 1920x1080. Maybe the VGA cable is faulty??? I'll try a different cable and post the results after breakfast!

We've had a lot of people post who end up finding out their issue was cable related, so it's possible.

Usually, the xrandr --verbose output lists the preferred and actual resolution of the monitor. All I see is the *current for the VGA.

Code: Select all

VGA-1 connected primary 1680x1050+0+0 (0x136) normal (normal left inverted right x axis y axis) 0mm x 0mm
1680x1050R (0x136) 119.000MHz +HSync -VSync *current
        h: width  1680 start 1728 end 1760 total 1840 skew    0 clock  64.67KHz
        v: height 1050 start 1053 end 1059 total 1080           clock  59.88Hz

It's possible the method you were using to add the lines might not have been quite correct because I see a listing for HDMI-2 even though nothing was connected?

Code: Select all

HDMI-2 disconnected (normal left inverted right x axis y axis)
  1920x1080_60.00 (0x14e) 173.000MHz -HSync +VSync
        h: width  1920 start 2048 end 2248 total 2576 skew    0 clock  67.16KHz
        v: height 1080 start 1083 end 1088 total 1120           clock  59.96Hz

It is similar to the listing for VGA-1 which was

Code: Select all

  1920x1080_60VGA (0x153) 173.000MHz -HSync +VSync
        h: width  1920 start 2048 end 2248 total 2576 skew    0 clock  67.16KHz
        v: height 1080 start 1083 end 1088 total 1120           clock  59.96Hz

How embarrassing. A different VGA cable worked perfectly. Sorry for the time waste!
While I'm here though, the Intel Windows driver has a utility for finely adjusting the contrast, brightness and colours. The controls on the monitor are not as effective. Is there anything in the Linux world to do something similar?

Good to hear it is working. Please go to your first post in this thread, click the pencil icon, and add [SOLVED] to the title so others know you are no longer seeking help on this issue.

I am not sure exactly what you are requesting, but I did a search on the forum for color adjustment and found these three threads:
Linux Mint 20 Color Calibration not working
[SOLVED] Intel HD Graphics Control Panel Color Adjustment Option in Mint
Improved an applet. Care to test?

Maybe something in those threads will help. If not, try a search of your own or create a new thread and maybe others can help. I've not really done work with color calibration.

Na... relax

. It's more often than not us humans encountered the final resolution being a simple one that we figured we'd think to test or catch earlier on in the troubleshooting process.

Keep sense of humor flexible like laughing fat cheek baby cheeks xD Happy you found solution !!
