[opensuse-factory] [Tumbleweed] VTx console on 2560x1600 monitor
The console on my new Linux box is coming up fine in the native resolution of the 30" monitor (2560x1600) and tells me it is using 300x100 characters. However, the complete last line plus about half of the second-to-last are invisible. Additionally, resizecons doesn't even recognis 320x100 as a valid resolution and the -lines parameter needs to dialed back to 60 for it to work. There's not a lot of documentation of how this is supposed to work with KMS, most of it even predates thze 3.x line of kernels. Does anybody know: 1. Why are the final lines not displayed and how to correct that? 2. How to make the VTx consoles use less than the full screen resolution? In other words is there a way to make it keep a border around the actual text area? At the moment I'm going to specify a smaller resolution for the console and set the monitor to 1:1 pixelwise display to work around the issue.

That works, but it also starts X in that resolution, so I'd have to force a different resolution in xorg.conf.d. I may still do this if no other soultion exists, but I would like to avoid that.

Does getting the display to auto-adjust affect those last 1.5 lines at all?
That works,
What exactly did you do to make that happen, using which resolution?
but it also starts X in that resolution,
This must be some new behavior I've been waiting to see for years and wondering why not.
so I'd have to force a different resolution in xorg.conf.d. I may still do this if no other soultion exists,
I nearly always do. It's not a big deal, except maybe if you're using the long broken Intel 2.99 driver. No Intel here obeys xorg.conf* as it should unless using the git3.0 driver.
but I would like to avoid that.
Which gfxchip? If not Intel, which video driver? Which cable connection type are you using? What clues are there in your Xorg.0.log? Everything here still responds to fbset from 12.3. Last I checked, no repo newer than 12.3 has it. If you install it, lock it, or updating will orphan it. -- "The wise are known for their understanding, and pleasant words are persuasive."

it's a digital display, so there is nothing to auto-adjust. The resolution it shows is correct and the pixels are there, just never get set different from background
That works,

By putting video=1920x1200-32@60 on the kernel line.
but it also starts X in that resolution,
This must be some new behavior I've been waiting to see for years and wondering why not.
Yes, I remembered that on my old machine w/ readeon it would query the monitor EDID instead and use the preferred resolution.
but I would like to avoid that.
Which gfxchip?
Intel Haswell (HD Graphics P4600/P4700).
If not Intel, which video driver? Which cable connection type are you using?
DP.
What clues are there in your Xorg.0.log?
It simply uses the initial mode that the kernel set up and never queries the monitor EDID. This seems to be as designed, maybe there is a parameter to have it do something different, but I don't know.
Everything here still responds to fbset from 12.3. Last I checked, no repo newer than 12.3 has it. If you install it, lock it, or updating will orphan it.
That's a new installation, so aside from fbtest there is nothing starting with "fb" in path. In any case, I don't think KMS uses either fb nor vesa for the console, so I'm not sure how useful it would still be.

I meant to ask before, which kernel? Maybe try the 13.2 release kernel and/or head, to see if the same.

It's already in the subject line: stock Tumbleweed, so kernel-3.17.2 and xf86-video-intel-2.99.916.

Well.. if they do not exist it is because kmscon is not installed. how do you suppose

At least kmscon/systemd-consoled has a maintainer which is actively interested in making things better and likely to fix issues you report. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Nothing. if you ln -s /usr/lib/systemd/system/kmsconvt@.service /etc/systemd/system/autovt@.service then the configuration in /etc takes precedence. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

OK, so I've shut down the existing VT manually and set up kmscon. While useful, it's missing quite a few things still: 1. The configuration directory is not created and no default configuration is there. 2. Without --hwaccel the switch from X to the VT does only work when switching through another VT still running agetty, so that should probably be made the default on systems that have capable graphics hardware. 3. There is a reference to a manpage kmscon.conf, but that manpage doesn't exist. This seems to be an upstream bug, however. 4. Without any configuration it comes up with US keyboard layout instead of the system keyboard layout. I'm not sure how difficult it would be to have it follow the system settings since I don't know if the configuration file accepts variables of any sort (see 3.). 5. Root cannot log in until the pam.securetty.so line gets commented out from /etc/pam.d/login. Arch Wiki helped me find that. 6. No description on how to set up a different color scheme other than mentioning some palette option that should not be used. Is there an alternative already? 7. No welcome message, so you don't know which VT you're on. But, it does solve the problem with the large screen not fully usable and it can use UTF-8 fonts in a sane manner. With some work on the color scheme and with tmux settings it might be quite the thing to replace X for system administration work.

Yes as you already noted, this has not gone through much testing yet and is in a fairly early stage but it is functional.
1. The configuration directory is not created and no default configuration is there.
Correct, this is a bug in the package mkdir /etc/kmscon.
2. Without --hwaccel the switch from X to the VT does only work when switching through another VT still running agetty, so that should probably be made the default on systems that have capable graphics hardware.
3. There is a reference to a manpage kmscon.conf, but that manpage doesn't exist. This seems to be an upstream bug, however.
Yes, you have to create a kmscon.conf in directory /etc/kmscon if you want some configuration.
4. Without any configuration it comes up with US keyboard layout instead of the system keyboard layout. I'm not sure how difficult it would be to have it follow the system settings since I don't know if the configuration file accepts variables of any sort (see 3.).
It should follow the system's configuration, I of course found the same problem as my primary language/keyboard layout is spanish.. it appears to be a bug. workaround i.e xkb-layout=latam in /etc/kmscon/kmscon.conf to get a list of layouts .. --> localectl list-x11-keymap-layouts
5. Root cannot log in until the pam.securetty.so line gets commented out from /etc/pam.d/login. Arch Wiki helped me find that.
Yes, pam_securetty is an anachronism from the telnet days. it does not really belong anymore.. it is dubious what "security" can provide anyway. if any restriction placed to access tty devices nodes is not enforced by the kernel itself (file permissions/ACL LSMs, .whatever) but by userspace .. game over! abandon all hope those who enter there! ;-)
6. No description on how to set up a different color scheme other than mentioning some palette option that should not be used. Is there an alternative already?
Not yet implemented apparently.
7. No welcome message, so you don't know which VT you're on.
Yes, a cosmetic issue..that may be annoying ;)
But, it does solve the problem with the large screen not fully usable and it can use UTF-8 fonts in a sane manner. With some work on the color scheme and with tmux settings it might be quite the thing to replace X for system administration work.
Note that kmscon is considered a research project. the actual guts of this userspace console is currently being implemented (by the same person who wrote kmscon) as libsystemd-terminal and the systemd-consoled daemon. apparently KMSCON will live on as a companion drop in tool for people that need fancy looking console/eye candy. This is still all in a early stage and very likely has major bugs,not to mention that changing components that rely on the kernel VT is also still a WIP. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Now that I switched to kmscons I see that already the boot messages (I boot with splash=verbose) have that problem, so it could also be plymouth. What was the magic kernel parameter to boot without plymouth again? BTW, I still get a normal agetty on VT1, how do I get rid of that?

If you just rename it .getty@tty1.service you can easily undo it if you don't like the effect. Most of my installations have 7 "files" in that directory, the original renamed hidden, and one symlink for each of the 6 ttys to make them behave as I wish. -- "The wise are known for their understanding, and pleasant words are persuasive."

This was likely a kernel bug since the recent update of Tumbleweed to 3.18.1 fixed this issue.
