arch linux Screen Resolution issue with xrandr

[ichase]

Been knee deep in the Xrandr Arch Wiki and have tried a number of things to change my resolution from the current 1366x768 to 1600x1200. Reason I am doing this is because I want to have more info in my conky and it ain't happening with the current resolution.

I am running a Dell Latitude E5510 which is MORE than capable of handling a higher resolution.

xrandr output shows:

[ichase02@arch64 ~]$ xrandr
Screen 0: minimum 320 x 200, current 1366 x 768, maximum 8192 x 8192
eDP1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 344mm x 194mm
1366x768	 60.0*+
1024x768	 60.0
800x600	 60.3	 56.2
640x480	 59.9
VGA1 disconnected (normal left inverted right x axis y axis)
HDMI1 disconnected (normal left inverted right x axis y axis)
DP1 disconnected (normal left inverted right x axis y axis)
1600x1200_60.00 59.9
HDMI2 disconnected (normal left inverted right x axis y axis)
DP2 disconnected (normal left inverted right x axis y axis) 

 

I have tried manually adding the resolution IAW the wiki but I get an error:

[ichase02@arch64 ~]$ cvt 1600 1200 60

I originally tried

[ichase02@arch64 ~]$ xrandr --output LVDS --mode 1024x768
warning: output LVDS not found; ignoring

To dynamically test some different resolutions but as you can see I am getting an LVDS not found.

 

So what do you think I am doing wrong here?

 

Thanks and hope everyone has a great weekend,

Have you tried installing and running arandr? I had some issues with setting the resolution on one of my monitors but I was able to use arandr (which is just a frontend to xrandr) to set the correct values (graphically). Arandr basically lets you set up xrandr visually then you can save it as a script. Here is mine (for reference):

#!/bin/sh
xrandr --output DisplayPort-0 --mode 1920x1080 --pos 1600x0 --rotate normal --output DVI-1 --mode 1600x900 --pos 3520x180 --rotate normal --output DVI-0 --mode 1600x900 --pos 0x180 --rotate normal --output HDMI-0 --mode 1920x1080 --pos 1600x1080 --rotate normal

 

 

If it works, then just add the path to ~/.xinitrc:

sh randr.sh &

(replace randr.sh with the filename you chose)

 

Wait, I just noticed that DP1 shows 1600x1200. Are you sure you are choosing the right output?

I installed the arandr package yesterday and only have 1366x768 to choose from.

No I am using eDP1. The reason you see a setting under DP1 is because I created it forgetting to add the "e" in front of it.

When I click "New" in arandr, nothing happens. I am guessing that is where you are talking about when setting up more elaborate settings.

Try this:

gtf 1600 1200 60.00

 

xrandr --newmode "1600x1200_60.00"  161.00  1600 1712 1880 2160  1200 1203 1207 1245 -hsync +vsync

 

xrandr --addmode eDP1 1600x1200_60.00

 

xrandr --output eDP1 --mode 1600x1200_60.00

[ichase]

When I get to addmode it fails:

[ichase02@arch64 ~]$ xrandr --addmode eDP1 1600x1200_60.00

What does xrandr -q show?

[ichase]

No clue why I am showing the 1600x1200 twice under DP2? Note there is no longer anything showing under DP1???????

I thought this was a laptop, so how does it have so many outputs?

I guess it's a really good laptop
