    Hi,
    btw i am using lenovo T410 with opensuse Leap installed.
    recently the taskbar is missing after re-login from unlock screen.
    sometimes i the screen went black then followed by shutdown.

    i check the log to find some error line, here is what i found

    i have tried to search on google, most of them will solved just by edit intel driver conf....
    but my laptop use different driver, its xf86-video-vesa, and i coulnd't find vesa driver configuration.
    i dont know if my problem related to type of vga driver that i use (vesa)...
    or should i change my vga driver, remove vesa driver and install xf86-video-intel driver?

    here is my vga specs
    Code:
    00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 02)
            Subsystem: Lenovo Device [17aa:215a]
            Kernel driver in use: i915
            Kernel modules: i915

    And why do you think so?
    These error messages come from the i915 kernel driver, which wouldn't be in use with vesa, which is just a generic fallback if no other driver is found.

    Please post your /var/log/Xorg.0.log .

    i've never choose vesa driver, and there was no specific notification to install specific driver while installing opensuse.

    sorry i put Xorg.0.log on pastebin

    Well, if you never chose it, why should it be used?

    According to you log, your system is using Xorg's built-in "modesetting" driver, which is preferred to xf86-video-intel nowadays especially on newer hardware (the intel X driver is just to buggy).
    Still uses hardware acceleration though.

    Your error message comes from the kernel module as I wrote.
    Might be a bug in the newer one from drm-kmp-default (backports from kernel 4.9), so try to uninstall that package.

    You may also try to install xf86-video-intel, maybe it would give better results.

    Other than that, you should file a bug report, as the error message tells you.
