Can only install and boot with nomodeset in kernel

Hi guys,

I am having trouble finding a way out of the nomodeset parameter in kernel. The only way to boot and to install Leap 42.3 in my notebook (Asus UX 305UA) is by adding nomodeset to boot parameters or i915.modeset=0. But I believe this has implications in the suspension mode of the notebook. When the computer sleeps, I just can’t wake it up as the screen remains black. I believe this has something to do with the OS loading with nomodeset. Strangely, one year ago I never had to add nomodeset to kernel, but it know seems as being the only way to boot linux, no matter it being opensuse, manjaro, or most others.

Here is the output from the command: /sbin/lspci -nnk |grep -A3 VGA

00:02.0 VGA compatible controller [0300]: Intel Corporation Skylake Integrated Graphics [8086:1916] (rev 07)
        Subsystem: ASUSTeK Computer Inc. Device [1043:1000]
        Kernel modules: i915
00:04.0 Signal processing controller [1180]: Intel Corporation Skylake Processor Thermal Subsystem [8086:1903] (rev 08)

It seems strange not having a line Kernel driver: i915. The notebook is equipped with a Skylake Intel processor and has ONLY integrated graphics (Intel HD 520).

Any idea on what can be done to solve the suspension mode problem?

Thanks!

Try the Kernel from kernel:stable Repo?

zypper ar -f http://download.opensuse.org/repositories/Kernel:/stable/standard/ kernel_stable

zypper dup --from kernel_stable

You’re right! The problem is that kernel packed with Leap 42.3 doesn’t work out of the box for my Skylake with Intel graphics.

Following your clue and directions found at https://forums.opensuse.org/showthread.php/522104-Secondary-Display I have added two new repositories:

zypper ar http://download.opensuse.org/repositories/Kernel:/stable/standard/ kernel:stable
zypper ar http://download.opensuse.org/repositories/X11:/XOrg/openSUSE_Leap_42.3/ XOrg

After adding repositories, I have done this:

zypper dup --from kernel:stable
zypper dup --from XOrg

Then, just followed the steps to install a new kernel 4.12.xx and replace the standard installed 4.4.xx
I removed nomodeset from kernel boot parameters and rebooted the notebook. Voila! There is support for the i985 chipset and brightness control. Now I can suspend session and wake it up without problems.

Here is the new output from /sbin/lspci -nnk |grep -A3 VGA

00:02.0 VGA compatible controller [0300]: Intel Corporation Skylake Integrated Graphics [8086:1916] (rev 07)
        Subsystem: ASUSTeK Computer Inc. Device [1043:1000]
        Kernel driver in use: i915
        Kernel modules: i915

Thanks!

Had the same problem this past Friday on a Gigabyte GA-X99 Phoenix SLI with a Gigabyte GTX 970 and Intel i7 5930K (Hashell). No Skylake or Intel graphics.

Install of 42.3 required nomodeset. After install and boot XFCE desktop had to much lag to use.

Install of 42.2 work with out any problems. Upgrade to 42.3 had the same problem. Needed nomodeset to boot, and desktop was laggy until I install NVIDIA Drivers.

After an almost problem-free install of 42.3, I experienced (almost) the same blank (NOT black) screen problem. The usual “Login” screen appeared, was totally unusable, then screen “blanked”, showing only a working cursor…

After booting with “Nomodeset”, and adding the current kernel from the “Stable” repo, all works as it should.
