Can not set proper resolution on this one monitor












2















I have a laptop with Intel HD graphics and running on Linux trusty 3.13.0-45-generic.



I never had problems connecting external displays to my Display Port, but now I got a new monitor and can not get my laptop to output the proper resolution.



The display is the Asus ROG Swift PG278Q.



When I run xrandr, all I get for the Display Port is



DP1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm

   1024x768       60.0* 

   800x600        60.3     56.2  

   848x480        60.0  

   640x480        59.9


Then I tried to add the proper mode manually, so I ran:



$ cvt 2560 1440 60

# 2560x1440 59.96 Hz (CVT 3.69M9) hsync: 89.52 kHz; pclk: 312.25 MHz

Modeline "2560x1440_60.00"  312.25  2560 2752 3024 3488  1440 1443 1448 1493 -hsync +vsync


Then added the mode:



xrandr --newmode "2560x1440_60.00"  312.25  2560 2752 3024 3488  1440 1443 1448 1493 -hsync +vsync

xrandr --addmode DP1 "2560x1440_60.00"


Upon activating the mode with



xrandr --output DP1 --mode 2560x1440_60.00


All I see on the display is the message



OUT OF RANGE


I also tried other resolutions and refresh rates with no success. On an other display my laptop manages 2560x1440p60 without problems. This particular monitor also works in this mode on a windows machine of mine.



Any suggestions on how to solve or debug this?

                    How to change which sound is reproduced for terminal bell?

                    3 Recently upgrade to 18.10 from 18.04, and using the terminal is becoming annoying: the new alert sound is a drip ( /usr/share/sounds/gnome/default/alerts/drip.ogg ), and the previous one is still located at ( /usr/share/sounds/ubuntu/stereo/bell.ogg ). My issue is that at the gnome-terminal, when autocompleting or pressing left BOTH sounds are reproduced, at the same time. I want to just have ubuntu/stereo/bell.ogg active, not both . At the moment I have been only able to reduce the volume of the alerts (but still both are played), or turn the alerts down (but I dislike both "solutions"). gnome-terminal 18.10 teminal-bell share | improve this question

                    Title Spacing in Bjornstrup Chapter, Removing Chapter Number From Contents

I think I'm fairly happy with the spacing around "A chapter", so I'd really like titles without descenders (e.g. "Contents") to have the same vertical spacing as "A chapter" below the title. I would also like to remove the large "0" in the contents title.
