Hello,

I tried to install Trisquel Alpha 8. It gave me a black screen after the instalation and i could do noting more than to see a black monitor screen. So i installed fresh Debian 9 GNOME (only main). But it doesn't recognize my screen resolution that is 1680x1050. It only displays 1280x1024. Anyone knows how to get 1680x1050 resolution?
In the past i tried the testing version of Debian(that is now the stable version Stretch) and i thought the error was because it was testing and not stable. So now we have Stable version and the result is the same...
You can see the file attachment below.
Thank you in advance.

Care to pierce the veil of secrecy regarding your hardware, maybe? I have an Intel graphics card with HDMI and it's supported on Debian 9. My display is properly recognized and the native resolution is applied.

I typed 'xrandr' and it gives a different output on X11 and Wayland.

Well.. i typed "xrandr" and it is the same...
i will try to change via terminal. May i ask if i do "xrandr -s 1680x1250" solves my question? I don't wanna try before until i hear from you.
Thanks

Well, these work with my display, but I have these modes in Xrandr's output.

What i did: First generate a "modeline" by using cvt. (below you see all my attempt in terminal)
Second telling to xrandr the newmode. But it failed.
I know for sure if i install Nvidia Drivers it will be ok. But i dont wanna this. In the past i installed APT Repository for Linux-libre of JXSELF. I was in that time in Debian Jessie. So i installed the 4.1 kernel Previous long-term support (LTS) version. And it worked like a charm.
But now with Debian Stretch, and doing "uname -a" the kernel is 4.9. I did with "sudo apt install linux-libre-4.9" and didn't worked as expected. I even tried after "sudo apt install linux-libre-lts" noting works!
The last resort i have is Nvidia drivers.
For instance, i tried Opensuse and *everthing* works.
I dont know what i need to do now. I got lost.
Thanks for your support.

Try with --addmode.

Arch has instructions on adding resolutions that are not detected.

What about Wayland login? It probably is wild goose chasing but doesn't hurt to give it a try.

Thank you for your reply loldier.
This is getting too much hassle and i dont have much more time to figure it out and i need to work with some urgency with my pc, so i installed nvidia drivers. It is running all well.
