Today's kernel update: monitor/display defaults to 1024x768

General system Kernel & Hardware
#1

After today’s kernel update, the monitor/display defaults to 1024x768 with no other options for my current monitor resolution.

It was working fine before the update. I did power off, reboot, no change.

I don’t know how to fix this.

Thanks in advance for any help.

Execute the command line and post the output:

lspci -nnk | grep -i "VGA\|'Kern'\|3D\|Display" -A3

I rather expected the problem kid proprietary nvidia driver.

Well, the driver is loaded successfully. You could write a .conf-file:

$ sudo mkdir -p /usr/share/X11/xorg.conf.d/
$ sudo -H leafpad /usr/share/X11/xorg.conf.d/20-intel.conf

Insert:

Section "Device"
	Identifier	"Sandy Bridge IGP"
	Driver		"i915"
	Screen		0
EndSection

Section "Monitor"
	Identifier	"FHD"
	Option		"PreferredMode"	"1920x1080"
	Gamma		1
EndSection

Section "Screen"
	Identifier	"Default Screen"
	Device		"Sandy Bridge IGP"
	Monitor		"FHD"
	DefaultDepth	24
	SubSection "Display"
		Virtual 1920	1080
		Depth	24
		Modes	"1920x1080@60"	"1366x768@60"
	EndSubSection
EndSection

Of course you have to set the native resolution of your TFT (in this example 1920x1080).

@axt

OK, I added this, making sure the resolutions matched the monitor.

Shutdown. Power up, it hangs at “/dev/sda1:clean…(files)…(blocks).”

I’ll have to go back in with a live disc later to delete it.

The message comes from fsck being run at boot time.

You should make sure to copy and paste all of it.

#8

Could you the output of command

lspci -vnn | grep -wP '0300|0302|0380'
#9

manuel, we already have this information. :wink:

#10

True, was too hasty reader…

#11

That is all of it, except for the digits. The cursor goes to the next line and that’s it.

I gave it 20 minutes and it did not change.

#12

Did you try using the other kernel, linux-lts? Worth a try if you didn’t.

#13

I mean c&p 20-intel.conf. Do not write-off, always copy & paste!

#14

After a lot of tweaking, testing, swapping out monitors (four different monitors, four different resolutions, four different manufactures), fresh OS installs of various distros, I finally noticed THIS:

display
display752×509 32.5 KB

I turned on the Connecting Displays switches.

So, for the past couple of days, with a couple of different distros, the proper resolutions are detected.
(I probably just jinxed myself by saying this. ^)

  • I’m still not convinced this is THE fix.

In my opinion, THE problem is this machine, an old Dell Optiplex I recently aquired. This is the first “factory” computer I’ve ever had. I’ve always built my desktops from hand-selected parts and have never experienced anything like this before.

NoDisplay=Dell

Never again

Great that you found the reason! :+1:
It is sometimes quite hard, as there are so many potential reasons.
