This begins to look like a DRMKMS issue. I'll try to look into this, but, we will need a kernel guru for this sooner or later. Try: 1. genfb/wsfb. 2. Since you have EDID and modelines, try running X blind with the "intel" display driver. This config fragment alone usually suffices: $ cat /etc/X11/xorg.conf.d/intel.conf Section "Device" Identifier "Card0" Driver "intel" # Option "AccelMethod" "UXA" Option "TearFree""on" Option "VSync" "on" Option "PageFlip""on" Option "SwapbuffersWait" "on" Option "TripleBuffer" "on" Option "LinearFramebuffer" "on" EndSection $ Explicitly supply a modeline and a full config file if the "intel" X driver fails to read the EDID.

Re: Issues with intelfb(4) and USB keyboards
hello. My apologies for such a naive question, but what driver should I use for the keyboard? The default, as created by X -configure, is "kbd" I'm thinking it should be "wskbd". Is that correct? In any case, the keyboard doesn't appear to work when X is running, though it works fine, using a USB keyboard and the wskbd driver when I'm using the console. I'll try the xorg.conf section you suggest and, if that doesn't work, i'll try the genfb driver. I'm hoping it's an easy fix for the i915drmkms driver, soon. Again, thanks for the help. -Brian

There's a work machine which according to RandR has seven outputs: DP1, DP2, DP3, HDMI1, HDMI2, HDMI3, and VIRTUAL1. VIRTUAL1 is, I believe, well, virtual. But, in terms of the connectors actually present on the case, there are two HDMI and one VGA. When the VGA is connected, one of the DPx outputs shows connected (I forget offhand which one). I don't _know_ that DP stands for DisplayPort, but it seems likely. So perhaps VGA looks like DP to software often enough? /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTMLmo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
Re: Issues with intelfb(4) and USB keyboards
hello. Below is the output of edid-decode against the data I extracted using your wsedid program. While I don't remember the exact numbers for this monitor, they look reasonable and, there is a dotclock value in there. The only thing that looks odd is that it says the monitor is attached to the displayport, which is incorrect. It's attached to the 15-pin VGA port. Perhaps that's normal, I'm not familiar with this graphics adapter. Anyway, what do you think?

That seems like a lot of text on a VGA screen.
The default font is 8x16 (WxH). So, on an 1280x1024 pixel display you

I wonder how BIOS/intelfb configured a 1280x1024x32 display without an
EDID. Might be a DRM-driver issue as mrg@ hinted. Let's look at your
EDID.
1. Get the edid-decode sources from https://git.linuxtv.org/edid-decode.git/
and compile it. It compiles cleanly on NetBSD.
2. Compile the program below, and run it like this:
./wsedid | edid-decode > /tmp/edid.txt
If the EDID and checksum look OK, then the DRMKMS driver will need
looking into. (And, in the interim, a program to set the correct
timings using libdrm may need to be written.--if you're not happy
with genfb.)
If they don't look OK, then unplug the CRT and try again. My old
ViewSonic LCD monitor has a "soft" off-button, and switching the LCD
off using that does no good when it's misbehaving.

I can probably find a dotclock value to use in this configuration, but I don't know how to put it in the i915drmkms driver. Can I put in a number with sysctl? I don't know of any sysctl for this. Nor do I know how to pass GTF/CVT modelines to the driver like you can do for Linux. The solution here might be to write a small program to use the DRM ioctls to set the desired mode (like with X and xrandr). I'll root around.
