Display resolution locked @ 1024x768 with Intel HD graphics.

English Hardware
1

Hardware: Z270 chip; i7 7700K; using internal Intel HD graphics.

The display resolution is fixed at 1024x768; if I go into System Settings->Display and Monitor->Displays->Resolution the current resolution is 1024x768 and changing this resolution is not permitted. I assume this is a driver issuer.

Does any one have any suggestions for the correct driver or do I need a later kernel. Thanks in advance for any input.

Does any one have any suggestions for the correct driver or do I need a later kernel. Thanks in advance for any input.

Sometimes using a later kernel is the solution, but first it might be useful to post the actual hardware chipset details

/usr/sbin/hwinfo --gfxcard

Examination of /var/log/Xorg.0.log might also tell the story here. It’s a lengthy file, so if you want to share that info upload it to https://paste.opensuse.org/ and post the URL that it provides here.

Okay, that cofirms that a basic framebuffer driver is in use and the display mode is set as

    47.381] (II) FBDEV(0): Modeline "current"x0.0   78.65  1024 1056 1184 1312  768 772 776 792 -hsync -vsync -csync (59.9 kHz b)

I’m not familiar with this generation of Intel hardware, but a quick search online identifies as graphics hardware which gained kernel from 4.5 onwards, so you could try upgrading to the latest stable kernel…

zypper ar -f http://download.opensuse.org/repositories/Kernel:/stable/standard    kernel:stable

zypper ref

zypper dup --from kernel:stable

then reboot.

See how that goes.

Kernel command line: BOOT_IMAGE=/boot/vmlinuz-4.4.62-18.6-default root=UUID=bd9501b5-e1e3-4d3c-8b3c-c0dd65c108dd ro resume=/dev/disk/by-uuid/74322b28-b628-41bf-91f6-0095fefe4bfd splash=silent quiet showopts

Question:
Why ro (read-only)

7

Though looking slightly confusing, this is not really a problem:

from man7 bootparam

(Or see bootparam(7) - Linux manual page)

     'ro' and 'rw'
              The 'ro' option tells the kernel to mount the root filesystem
              as 'read-only' so that filesystem consistency check programs
              (fsck) can do their work on a quiescent filesystem.  **No
              processes can write to files on the filesystem in question
              until it is 'remounted' as read/write capable,** for example, by
              'mount -w -n -o remount /'.  (See also mount(8).)

              The 'rw' option tells the kernel to mount the root filesystem
              read/write.  This is the default.

During system setup this remount is done by the init system and according to the respective fstab entries (most likely with / being mounted rw). Some distros use(d) that even as their default (last time I tested Arch it certainly was default there, but that is some years ago).

Just give it a quick try without making it persistent, even with “ro” as boot parameter the root partition will be mounted “rw” when the system is up.

Thanks Deano installing the latest stable kernel fixed the display resolution issue.

Good to read of your success with this. :slight_smile:

I had the same problem on one box with a fresh install of Leap 42.3. I updated the bios for the motherboard and then reinstalled. That solved the problem.

I always check and see if there is a bios update for the motherboard and then apply it, especially on the older boxes. This can be much easier fix than mucking around with the kernel which could break something else.

That won’t help for a graphics issue like this where kernel support was lacking.
