display resolution under Trisquel 11
I have been running my t430s with trisquel 10.
after the installation (reinstallation, clean) of trisquel 11, i am no longer able to select my usual resolution of 1600x900.
i have already upgraded to Kernel Linux 6.5.0-45-generic x86_64. no success.
then i tried to add the mode. for this i read the modeline of my other identical t430s, which is still running under trisquel 10 (xvidtune -show), created it with gtf under trisquel 11 and added it (xrandr --newmode “1600x900_60.00” 119.00 1600 1696 1864 2128 900 901 904 932 -HSync +Vsync)
i can now change the resolution. however, the display is then very blurry and the font is difficult to read...
are there other solutions?
in system monitoring, “Mesa Intel® HD Graphics 4000 (IVB GT2)” is displayed under 11 and “Mesa DRI Intel® HD Graphics 4000 (IVB GT2)” under 10.
Please share the output of:
lspci -nnk|grep -A4 "VGA compatible"
It is very possible that newer drivers enable some Intel Graphics Micro(µ) Controller, depending on your graphics card generation and it may rely on firmware blobs not present in Trisquel.
So having the right model we might be able to find more information and a possible workaround on this issue, more common with newer hardware.
here is the output:
VGA compatible controller [0300]: Intel Corporation 3rd Gen Core processor Graphics Controller [8086:0166] (rev 09)
Subsystem: Lenovo 3rd Gen Core processor Graphics Controller [17aa:21fb]
Kernel driver in use: i915
Kernel modules: i915
THANK YOU!
Oh, 3rd generation, that's old school i915, it should be working correctly.
I have one:
00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0126] (rev 09)
Subsystem: Sony Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [104d:907b]
Kernel driver in use: i915
Kernel modules: i915
Working with 1920x1080 and an external monitor via HDMI also 1920x1080.
It's around Gen 9 and forward that the behavior described above start to show up.
Anything suspicious on dmesg?
the only about video on dmesg is:
ACPI: video: Video Device [VID] (multi-head: yes rom: no post: no)
[ 1.946831] input: Video Bus as /devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/LNXVIDEO:00/input/input6
nothing about display...
on trisquel 10 it was working out of the box
no further ideas for a solution?
i especially don't understand how it could work in trisquel 10 and now not in version 11??? there were no errors in this completely new installation with the latest ISO from the website (MATE)...
