Video driver x302ua

[sabur]

Hi all. On hands have a notepad x302ua with video intel hd 520. For win10 driver works fine, no problem, today installed debian 9.2. At the first blush video work without trim, quickly. Question, how to check if the driver is installed correctly (mesa-utils installed) and everything works right. Maybe exist programs for test correctly installed video driver or command in console. Thx

Your device should be using the kernel's built in modesetting driver for your Skylake 520 video instead of xserver-xorg-video-intel. It is recommended that you add non-free firmware for that device, as well as intel-microcode.

I'm not sure if that "i915" driver is modesetting or the xorg one, but I think it's the xorg one. This leads to the question, why is it doing that?

Install inxi and give the output of

Code: Select all

inxi -F

[sabur]

Code: Select all

admin@host:~$ sudo inxi -G
Graphics:  Card: Intel HD Graphics 520
           Display Server: X.org 1.19.2 driver: N/A tty size: 190x46 Advanced Data: N/A for root

On Antergos linux for comparison sudo inxi -G (with installed mesa-demos)

Code: Select all

Graphics:  Card: Intel HD Graphics 520
           Display Server: X.Org 1.19.4 drivers: intel (unloaded: modesetting,fbdev,vesa)

Penalty of ten Debian points for running a command with sudo when the instructions said nothing about that. That's a very very very bad and potentially dangerous habit. Please run it as instructed, as parts of the output are blocked in Debian when running with sudo or as root.

Some confusion right there. Kernel modesetting (KMS) is not Xorg driver. KMS is mandatory for all Xorg FOSS drivers nowadays. Only nVidia blob works without it, as a matter of fact, it has its own KMS. Running Xorg loads another modesetting driver, which is a modern replacement for xf86-video-intel. Although some claim Intel driver still has edge over modesetting.

But I took care not to call it kernel modesetting! Debian calls it modesetting..what do you propose?

More to the point, that's the driver that is supposed to show up when inxi is run correctly in Debian for Skylake graphics, not the i915. Unless it's forced in a configuration file like 20-intel.conf and the like.
