ASUS P756U - display resolution

English Hardware
#1

Hello,

I have installed openSUSE Leap 42.2 on a new ASUS P756U notebook. It comes with a high resolution display of 1920x1024.

But the highest resolution I achieve is 800x600.“Nomodeset” at boot time dows not help either.

Here is the output of hwinfo --gfxcard:

Primary display adapter: #8

I know that a better resolution is possible, as I have installed Mint as a dual-boot-option; with Mint I can get the full resolution but not with openSUSE.

Does anyone know how to fix that?

Thank you

Nomodeset with Intel, Radeon or Nouveau can not help, those drivers need the Kernel Modesetting.

So delete it from grub2.

And restart your Laptop.

Post then:

cat /var/log/Xorg.0.log

As I can see, those Graphics works only with Kernel 4.5 and above.

Post:

modprobe -c | grep -i "8086.*5916"

If you get no Output, maybe you install the Kernel from kernel:stable Repo:

Hello,

thank you for your help.

I have posted the output of Xorg.0.log to http://susepaste.org/35685280

@Sauerland: thanks for the hint about the kernel version, but Mint has kernel version 4.4.0 and the display resolution is OK there.

Perhaps Mint has backported kaby lake support. If you posted the xorg log based upon your experience with Mint, you’re ignoring what was conveyed in the other thread about what happens in openSUSE Leap. Suggest you read through it, as your available solutions are outlined.

Hello All,

I finally managed to install kernel 4.9.x.x. It took a while but now all is perfect!

Thanks to all of you for your help and advice!

Will have to close this ticket somehow?
