The "failure" occurred when using the dell docking station and display
port from the dock to the monitor.  I booted into windows (first time in
over a year) and the same cabling worked perfectly for 3440x2500.

I have now ditched the dock and am running hdmi directly from the laptop
to the monitor and again success at 3440x2500.

I will soon try Canek's suggestion of setting VIDEO_CARDS and using the
built-in drivers.

Yes, but I am missing some info:

Is sda1 marked as ESP?

Also, you should mark sda3 as root partition through gptfdisk.

That way, any modern EFI boot loader should be able to auto-configure
everything.

I think you need a working initrd for auto-detection to work. At least,
systemd is able to assemble the partitions from GPT partition type
settings and can autodetect boot, swap and rootfs.

Otherwise, you should give at least a root= cmdline.

This puzzles me, too... Maybe rEFInd was installed to sda and grub
installed to sda1, so rEFInd would chain-boot through grub.

Grub, however, won't work without a config file. I'd also suggest to
skip grub completely and use just one loader.

Yes, this is not helpful. How could one expect us to be helpful if
she/he refuses to give details? Nobody requires to copy the screen
contents by hand. For me, a useful screen shot taken with a mobile
phone camera would be a first step.

I think there are even services which can OCR such a screen shot...

Re: [gentoo-user] new hi-res display won't work at top res

[Canek Peláez Valdés]

You don't need the Intel graphics driver, they are actually deprecated [1].

Just set your VIDEO_CARDS to:

VIDEO_CARDS="intel i965"

and do emerge -uDNvp @world; when you do emerge --depclean,
xf86-video-intel will be uninstalled.

The built-in modesetting driver is the one recommended; I'm pretty sure it
will support the maximum res of your new monitor.

I think i965 is the better driver for your system, not i915.

Which connector are you using? HDMI output of your laptop is most 
likely limited to 2560x1600. I checked and many Latitude ultrabooks 
have a displayport (of mini variety generally) output. If you use 
that connector you may get the resolution you wanted (you may still 
need newer drivers).

  I was using a chroot, and I bind-mounted the chroot's /dev and /proc
and /sys on top of the host machine's directories.  Bad idea... I now
have a 10 megabyte /dev/shm on the host.  Is it possible to resize
/dev/shm to approx 1 gigabyte without rebooting?

  And how do I set up a working /dev and /proc and /sys on the chroot

Are you letting rEFInd auto-detect it? Maybe you need to configure it
manually with a root= setting.

You said you were using rEFInd, why have you got GRUB as well. rEFInd can
work without a config, GRUB cannot.

That's a summary, not an exact message. As such it gives no useful

For UEFI boot the best way is to install the kernel to the ESP,
especially if it is directly loaded by EFI. Which exact message do you
see? It is not clear if the kernel already booted and just cannot find
the rootfs, or if even the kernel cannot load.

I don't know reFind, but some EFI loaders like gummiboot / systemd-boot
expect the kernel to have an EFI stub because the kernel is
chain-loaded through EFI...

So we need to know a few things:

1. partition layout
2. kernel cmdline
3. boot-loader config
4. exact error message on screen

Re: [gentoo-user] Kernel did not finding root partition

[Rasmus Thomsen]

Hi,

make sure you have XFS compiled into the kernel ( not as module), or include it 
into the initramfs ( dunno how you would do that with genkernel though, I don't 
use an initramfs ). Grub should include a line saying root=xxx, maybe you have 
to set rootfstype, had to do that for BTRFS. Also make sure that you have sata 
( or nvme if you use that ) compiled into your kernel.
