Ubuntu 14.04 does not support 2560x1080 resolution.

[Ian Shaw]

I recently installed Ubuntu 14.04 on a mac mini and bought a 2560 x 1080 ultrawide LG monitor for it. Problem is that it doesn't display the proper resolution, the maximum being 1920 x 1080 under ubuntu settings.

Any suggestions on what I should do?

Please give clear instructions as I am not an Ubuntu expert.

My graphics card: NVIDIA Corporation C79 [GeForce 9400]

If there is currently no solution, would someone please pass this on to the Ubuntu developers so that they start working on implementing this resolution into the operating system?

Thank you,
Ian

I don't know that much about packages... I hope "xrandr" covers it...

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Vpispanen (vpispanen)]

Also affected on Nvidia GeForce 330M (with proprietary driver v. 331, maybe with nouveau) on Ubuntu 14.10

[Payam Nab (papampi)]

Not working on 14.10 either

[Payam Nab (papampi)]

Max res I could get for my 29" ultra wide is 2160x912

[Jaufré Aligé (jaufre)]

now you can use nvidia proprietary driver 346

Just use our friend Michael Marley's ppa :

Add ppa, update cache, install nvidia-346 and reboot :
sudo bash -c "sudo add-apt-repository ppa:mamarley/nvidia -y && apt-get update && apt-get install nvidia-346 -y && reboot"

I hope nouveau will improve...

Do you have any solution for ATI graphics card?

[Jaufré Aligé (jaufre)]

I tested it with hdmi display. However, I can't guarantee it will work with a pre-kepler card.

[freeman (wielki-freeman)]

I have Nvidia GT330M and I have very similar issue: http://askubuntu.com/questions/665566/ubuntu-15-04-sees-2560x1080-resolution-only-sometimes

but the latest graphic driver for my card is 340.76.

Do you have any solution in this situation?

[hodja (ehodja)]

Any update for this bug?

[mohsen (sm-zahraee)]

i also have this problem, is there any solution? i use dvi port.

Also problem, running 14.04 LTS with 9800GT and LG 2560x1080 monitor as my primary in a dual-display setup. I was able to get that res by reverting to non-nvidia drivers, but otherwise, still a bug.

[Michael Roberts (hu6hzq0zv-7aoyaz9-t16qijz8x)]

Same here on 14.04 LTS with an LG 29UM58 ultrawide monitor through a Radeon Cedar graphics card and HDMI. Thanks to @papampi for the 2160x912 workaround, I can actually use this rather nice new monitor, though.

[Haemin Yoo (mariceles)]

Seems like a long-lasting bug, and it seems I've stuck with it too. I am using an HDMI cable to connect my laptop with the monitor. Hope it gets a fix soon so I will be able to come back to linux once again.

Seems that also on LG ULTRA WIDE it is a problem to use it's resolution using GTS 250 GeForce.
I was almost convinced that my video card was the problem.

ubuntu 16.04
maximum resolution allowed on ultrawide is 1920x1080, I was able in the past to see 2560x1440 resolution but when changed screen goes to black.
video driver: nVidia 340

[Stan Syritsyn (staleo)]

A 29-inch LG 29um67-p with an on-board piece of legacy Radeon Sapphire 6670, don't work all together.

Ubuntu 16.04, max resolution in settings is 1920x1080. I try to manually include a 2560x1080 mode via xrandr, but after I apply a mode in terminal, the screen turns weird just like if I picked random digits for the resolution. Completely impossible to work.

Sad to see a bug was submitted almost 2 yrs ago, and seems no result yet. :/

[Simon Brodeur (sbrodeur)]

I have an external LG ultrawide monitor (21:9 ratio) connected through HDMI on my laptop with integrated Intel graphics. I adapted a script from this thread to support for 2560x1080 (60Hz) resolution:
http://askubuntu.com/questions/727753/how-do-i-configure-ubuntu-for-a-219-screen

It would be useful if the resolution was automatically supported. It works perfectly in Debian Jessie (Gnome).

--------------------------

#!/bin/bash

# Setup external monitor resolution at 2560x1080 (60Hz), if connected
RESOLUTION="2560 1080 60"
OUTPUT="HDMI-1"

CONNECTED=$(xrandr --current | grep -i $OUTPUT | cut -f2 -d' ')
if [ "$CONNECTED" = "connected" ]; then
    MODELINE=$(cvt $RESOLUTION | cut -f2 -d$'\n')
    MODEDATA=$(echo $MODELINE | cut -f 3- -d' ')
    MODENAME=$(echo $MODELINE | cut -f2 -d' ')

    echo "Adding mode - " $MODENAME $MODEDATA
    xrandr --newmode $MODENAME $MODEDATA
    xrandr --addmode $OUTPUT $MODENAME
    xrandr --output $OUTPUT --mode $MODENAME
else
    echo "Monitor is not detected"
fi

Ubuntu 14.04 and 16.04 are no longer supported. Anyone using Intel graphics and a newer release should refer to bug 1901470 instead. Everyone else, please open a new bug if you encounter problems.
