Acer Aspire 5740g resolution not found

Acer
Intel

#1

I have just installed ubuntu mate 18.04 on an Acer 5740g with a 1366x768 display and an Graphics: Card: Advanced Micro Devices [AMD/ATI] Park [Mobility Radeon H

D 5430/5450/5470] .

Unfortunatly i don’t have the right resolution (defaults to 1024x768, and 1366x768 isn’t avaible).

So i have followed this tutorial -> https://askubuntu.com/questions/442851/how-can-i-get-my-monitors-maximum-resolution-without-the-proprietary-amd-graphi

And works fine, but every time i turn on the pc i get an annoying window, i attach screenshot. It disappears magically, but nevertheless i don’t like it :wink: . How can avoid this window? Thank you in advance.

#2

I have tried to delete ~/.config/monitors.xml and it reverted to 1024x768, without the annoying window.

After choosing again 1366x768 and rebooting, the problem appeared again.

Sometimes i have also an apport crash for lightdm :frowning:

Edit: the error in english installation should be “Could not apply the stored configuration for the monitor”


#3

A little update: Even with ubuntu mate 18.10 (tried from usb) the native resolution isn’t found.


#4

Hi. Search on google ‘marius ciclistu native resolution ubuntu’ and on ask ubuntu you’ll see a solution to a similar problem I had.
Also, in my case, the driver I used is nvidia.


#5

Thank you, but i’m not using NVIDIA, and after all i’ve got the right resolution, and there isn’t an xorg.conf file…


#6

Good to know you solved it. That config file is generated when you run the command mentioned there.


#7

Thank you but i don't have nvidia config, and i haven't solved the problem.

Btw, i post here the links to your posts: https://askubuntu.com/questions/712116/how-to-set-up-native-monitor-resolution-of-1680-×-1050-with-nvidia-geforce-210-o


#8

Try to check the horizontal and vertical refresh rate for your case. You should have 2 drivers for display. Nouveau from ubuntu and the proprietary one for your drafics. Try on both.


#9

It's an ATI. And i've been able to get the right resolution. The problem is the window you see in the screenshot.

I gues, that is because you chose a resolution above the max one, as the message from that window states. My problem was similar...
