Hello,

I have installed Fedora 20 on a Lenovo y400. Works great but the display resolution I get is 1024x768 and I don't have the option for 1368x768 which is my laptop screen resolution.

When I boot with Kernel 3.11.10-301 instead of the default 3.13.9-200 I get the correct screen resolution: 1368x768.

I have tried the gnome, kde and xfce desktops but got the same problem with all of them.

Can somebody give me some indication on how to get the 1368x768 screen resolution with the default Kernel 3.13.9-200 or what may be the problem here.

UPDATE 2014-04-20:

This is the Xorg.0.log file after booting with the 3.13.9 Kernel and -wrong- 1024x768 screen resolution.

This is the Xorg.0.log file after booting with the 3.11.10 Kernel and -correct- 1368x768 screen resolution.

After booting the kernel in question, upload /var/log/Xorg.0.log to http://fpaste.org , you can use this command in terminal:

fpaste /var/log/Xorg.0.log

and post the link it'll print here.

Hi Ahmad, here's my Xorg.0.log.

The log indicates that KMS (kernel mode setting) is disabled for some reason, so the default nouveau driver can't be used and the system is falling back to the very basic vesa driver.

Let's have a look at dmesg:

dmesg | fpaste

Thank you Ahmad, here's dmesg.

The problem is likely Fedora's outdated nouveau. I had a similar problem with Fedora 20 running vesa for my GeForce GT 635 card and getting only 1024x768. The Ubuntu live CD runs the same system at 1920x1080 with its newer nouveau. The Ubuntu nouveau is 1.1.1, Fedora 20's is 1.0.9.

I guess you mean nouveau 1.0.10, this the latest I can find in upstream git.

I think your issue is different than mjrofra; his problem is with the newer kernel, i.e. something that changed in the nouveau kernel module, since his card works well with the older kernel. Whereas your issue is that the nouveau X driver, 1.0.9, didn't recognise your card and the newer 1.0.10 supports it now according to the upstream git commit log.
