[SOLVED] Screen refresh in terminals emulators is SO slow

moige · 2018-01-16 00:00:37

The screen refresh when I do ls /bin/ in terminal is SO slow. I guess is a problem with framebuffer? I do thought is a problem with framebuffer? I activated VESA, but nothing has been change.

Nothing band happens, I guess.

/etc/X11/xorg.conf.d/20-intel.conf

    Section "Device"
    	Identifier  "Intel Graphics"
    	Driver      "intel"
    	Option	    "DRI"	         "3"
    	Option      "AccelMethod"    "uxa"
    	Option	    "TearFree"       "true"
    EndSection

VAAPI influences in this? Because, AFAIK, VAAPI is not possible with i915 driver. KMS or DRM configuration?, MESA or VULKAN need to be care?

Is slow with wathever command that demand a heavy use of terminal screen. VIM is very affected by this problem, some times get very time to upgrade the new text that I entry (without code highlight and anybody plugin).

$ time ls /bin/
    
    real	0m4,042s
    user	0m0,038s
    sys	0m0,111s

When I exit of X11 I get:

    real    0m1,568s
    user    0m0,009s
    sys 0m0,744s

Thanks in advanced for helping.

You're using the intel x11 driver? Try removing it (and it's config file) so X just uses the built in modesetting driver. The latter performs much better under most conditions.

You mean the xf86-video-intel? In that case: Yes. So, just remove and nothing more about configuration to use modesetting?

Trilby · 2018-01-16 00:23:24

Yes, remove that package, then remove 20-intel.conf and restart X - you should then be using the modesetting driver which should be able to be confirmed in your xorg log.

If you have vesa or fbdev installed it might try to use those first - so you may need to remove those too if they are installed. The modesetting driver is built in, so no x11 driver package is needed. Modesettings is generally the recommended default for intel graphics lately.

Ok. I do that you say, but when I try to start X11 without intel driver and without intel conf, X11 just not start.

It seems to be a problem with glamor aceleration?

Odd. I'm not sure what to make of that error - but it has shown up in another current thread:
https://bbs.archlinux.org/viewtopic.php?id=233474

How do you start x and what DE/WM are you using?

Do you have `mesa` installed?

Update: I finally can start X11 with modesetting and framebuffer perfomance is resolved. I just make a 00-modsetting.conf and disable AccelMethod because glamor is falling in my device. The only problem is that the resolution is lower than my monitor can, but is irrelevant to this problem; that can be easily solved with xrandr.
