Kernel 4.11.0-rc7 - Slack64 Current - i6700 Graphics 530 (rev 06) - requires nomodeset


Anyone running kernel 4.11.0-rc7 on Slack64 Current on an intel i7/6700 with onboard Graphics 530 (rev 06)? For me it requires the nomodeset kernel boot parameter.
Funny thing is that the same kernel on the same hardware but with a 32-bit 14.2-like userland (PartedMagic) runs ok without the nomodeset.
As the xf86-video-intel versions differ (PM git_20170228 vs Slack git_20170313) I built the PM one for Slack64, but to no avail ...

Try using the modesetting ddx included with the xorg-server instead of xf86-video-intel.

I experimented with the modesetting ddx (/usr/lib64/xorg/modules/drivers/modesetting_drv.{la,so}) via an entry in /etc/X11/xorg.conf.d, but to no avail ...
For as far as I am aware this replaces the *xorg* driver, but the black screen occurs when eudev makes the *kernel* do the mode switch, so much earlier. Actually I boot into level 3, so no X initially.


As an aside: returning from a suspend does not work either.

Yea, the modesetting ddx tends to be (Sometimes?) better supported upstream than the various individual xorg ddx drivers. Though I guess we know what the issue is not then.

What was the last working kernel for you? I guess you could ask the intel devs directly in #intel-gfx @ freenode.

The 4.10.11 kernel works without a hitch (no nomodeset, return from suspend ok) for me.
When scanning the DRM/Intel Bug List at Freedesktop.org (google for "intel i915 drm bug") for 4.11 I found "Bug 100383 - [i915][BYT] Black screen in mainstream kernel 4.11.rc3 on Toshiba LX0W-C64", which looks like my problem - though that is an atom instead of my i7. Alas no resolution as of yet.
If things come to the worst I can always skip the 4.11 kernel.

Slackware64-current, 4.11.0-rc7, 6700K with onboard Graphics 530, dual monitors.

Both runlevels 3 and 4 work fine, w/o nomodeset boot parameter. For X I use the modesetting driver.

Mine is a i7/6700 (w/o the "K") with a single monitor.
I also tested the Slack64 image on my other desktop and laptops - all of them with older intel onboard graphics: no nomodeset required and return from suspend ok.
