  • Hello :)

     

    I faced unusual problem with my intel hd graphics; The problem is...

    I am facing blurry fonts and images and videos on my LCD; At first sight it seems like videos are lack of colors but color quality is 24... Visually fonts are not as black and clear as they should be, moreover, the screen is a bit flashing or shaking (?not too fast (+/-) 1-2 px artifacts "http://techreport.com/forums/viewtopic.php?f=37&t=86271&start=30#p1153405" repaint for non-moving items) which causes my eyes strain after 20-30 min of watching...

     

    Prehistory:

    Previously I had elementary OS Luna x64 bit with kernel 3.13 installed so the screen was more clear and all fonts and images were normal but my hardware needed more new kernel so I had to move on manjaro OS x64 which is based on arch OS...

     

    ...But manjaro's official intel drivers cause the blurry effect which is much annoying (please see attached photos) So I am stuck here Now I do think maybe I need to downgrade intel video drivers to those which elementary OS had but I don't know which drivers versions my video card requires? So I need your experienced advice of :

    • A) How can I analyse my notebook (asus x551m processor N3520) to find out what graphics card I have cause lspci just outputs "VGA compatible controller: Intel Corporation Atom Processor Z36xxx/Z37xxx Series Graphics & Display" but I am not sure is the info enough to choose proper video driver version?
    • B) how can I find out what linux intel graphics driver version I must install ?
    • C) If I just need to upgrade one of drivers (all drivers) to fix the problem how do I know that and how do I upgrade it manually cause official repo-s c stable and git ones only?
    • D) If I need to post-install some additional package please let me know
    • E) If I need to know more to solve the problem please guide me

    Currently installed drivers :

    • Mesa - 10.3.1-1
    • xf86-video-intel - 2.99.916-3
    • Libdrm - 2.4.58-1
    • Libva - 1.4.0-1
    • vaapi intel-driver - //? cannot find with package manager
    • Cairo - 1.12.16-3 //? have it in repository but it is not installed cause I have cairo-infinality-ultimate 1.14.0-2 installed
    • Xserver Xorg - (xorg-server 1.16.1-1 and xorg-server-utils 7.6-4 )
    • Intel-gpu-tools - 1.8-1

     

    Concerning video card :

    lspci | grep -e VGA -e 3D 00:02.0 VGA compatible controller: Intel Corporation Atom Processor Z36xxx/Z37xxx Series Graphics & Display (rev 0c)

     

    p.s. please don't send me to manjaro.org cause it is intel graphics and linux specific issue which requires intel hd graphics expert advice; I really hope for your help describing the issue because all my questions related to this problem on non-intel forums are still unanswered ; So I am glad to hear any helpful tip or comment; If you need to know some additional information please let me know...

     

    Thanks

  • Hi - this isn't really an installer related question, so you might want to take it to the advanced forum, but as you're here:

    The i915 driver doesn't really have a version separate from the kernel it ships with,
    so if a 3.13.x kernel was working for you before, that might be what you want to try.

    However I'm not sure it's the i915 driver at fault here: As you have noted in your message,
    there are many components involved, and it could be one of those. Let's address youe questions:

    A) How can I analyse my notebook (asus x551m processor N3520) to find out what graphics card I have

    lspci -vvnn will tell you in greater detail exactly which chipset you have, including the PCI ID.

    B) how can I find out what linux intel graphics driver version I must install ?

    In general it's only ever the i915 driver, which supports both the i915 and i965 families.
    The driver is released as part of the linux kernel, and generally the version tat comes
    with your kernel should be fine.

    C) If I just need to upgrade one of drivers (all drivers) to fix the problem how do I know that and how do I upgrade it manually cause official repo-s c stable and git ones only?

    Since the driver is part of the kernel tree, it can be quite involved to get a newer or older driver,
    as it can be quite closely tied to the kernel version. Your best bet, should it really be the driver
    that's at fault, is to install a different kernel, ideally one packaged by your distribution.

    D) If I need to post-install some additional package please let me know

    Shouldn't bre necessary.

    E) If I need to know more to solve the problem please guide me

    I would start by looking at things like the configured resolution of your
    display - does it match the actual screen. Things like anti-aliasing for
    LCDs may also be configurable through your display preferences,
    typically made available through some sort of "system settings"
    menu or application.

    HTH.

  • I had the exact same problem. Did you have written and I did not help. When the updated BIOS everything worked as it should. The HP 15-d050sr.
