you need to tell x11 to do the same
That has nothing to do with the booting process, and besides that is
and was working no matter what boot loader I use. I was hoping to
avoid efi boots but it looks like I am doomed if I want 4k boot menus
and the such. It's the penguins that really tell the tale.
that will create a new xorg.conf, no ?
How does that help the booting process, especially considering 16 4k
efifb penguins? Speaking of which I calculate exactly 30 possible penguins on a 4k monitor assuming they are 128 pixels wide which
matches with my observation of the current 16 boot penguins I am
seeing on bootup ( 3840/128 = 30 ). Now all I want is a sun36 consolefont for it and my new desktop will truly be awesome. One
thing is for sure; a fullscreen console based mplayer (-vo fbdev2) on
a 4k monitor looks really, really good. It can play x264 encoded
files .. still no x265 support. So far that hasn't mattered but I've heard of a few digital cameras that output x265 and that might be more significant to them.
For the record, 16 boot penguins will also fit in a 1080p (1920 x
1080) monitor with room for 4 more (20 total). The math is a bit different since it looks like 96 pixels wide penguins are deployed at that resolution ( 1920/96 = 20 ). If 720p uses the same width then it can only display 7. Assuming 48 pixel width then only 15 penguins are possible for display purposes. `Tis sad but true. Oh well ... 1080p
is noticeably sharper than 720p on 7" monitors.
Life is good,

no hint with this ?
why keep the booting process fokus ? :=)
imho vga and mode is needed in kernel boot options
What hint are you looking for? I already posted about grub's gfxmode
and the kernel's efifb but if more is required I am sure it is doable.
I just need to know what you're looking for.
why keep the booting process fokus ? :=)
Becuase that is where it starts,
far as linux is concerned. However I always like to see the right
thing happening as soon as the power is switched on.
Now that it is
working I am content to move on to better things such as runtime apps.
Having said that mplayer is already working so I can't think of what else might be required as far as 4k monitors are concerned.
imho vga and mode is needed in kernel boot options
That shouldn't be a problem. Anyhow I've now tested three different monitors on this setup and they all do the right thing except that a
720p monitor cannot display 16 penguins given the shortage of pixels. 1080p works great with room for 4 more (20 total) in it's native
resolution. 4k could use a tad larger consolefont but
latarcyrheb-sun32 is readable methinks. It is what I am seeing as I
type this reply.
its long time since i have see the penguins on gentoo
gentoo splash screens and wallpapers want the penguins to live
aswell
you only need kernel boot initramfs to enable it with the mode=
and vga=
want all in fb0 ?
i only have a display port monitor at fullhd, 4k is nice and
expansive :=)
its long time since i have see the penguins on gentooSame situation here although it didn't really matter as far as working
4k graphics are concerned.
gentoo splash screens and wallpapers want the penguins to liveI am sure it could ( does? ) work. I'll see what I can find out
aswell
later.
you only need kernel boot initramfs to enable it with the mode=It doesn't work here as those only supply standard resolutions. 4k is not an option.
and vga=
want all in fb0 ?Sure why not? However xorg still works and "mplayer -vo vdpau -fs movie.mp4" gives a fullscreen 4k on xorg that is worthy of note. I assume other graphically inclined applications will also work.
i only have a display port monitor at fullhd, 4k is nice andYes it is. For the cost of a half decent 28" 4k monitor I can easily purchace two top-of-the-line 1080p monitors.
expansive :=)
As for the 7" monitors I
have, the 1080p is definetly the better compared to the 720p. The smallest REAL 4k monitor I can find is a 12" and they want far too
much money for it, almost twice the price of the 28" one I now have.
Four of them? I am going to have to pass on that.
I am glad I did this as now I know and am content to have one working
4k monitor but I am unlikely to replace it with another. 1080p is
more than good enough for my usage for graphics, and is far cheaper. That is my recommendation at this point in time.
if i get a 10 meter long hdmi cable i could test it
and still have usb c ports to be used as monitors ports :=)
screens can be transportable, hehe
so you miss firmware ?, or just a asus pn50 ? :)
also links -g https://localhost/mypicture.jpg :)
i have a 49" android tv, cheap :=)
but it is expansive if it just a monitor, hmm
rasberry pi 7" touch screen ?, i have one of them, still
planning on create something with it
yes it nice, olso on hollydays :=)
you will see bigger diffrent on bigger screens
would you share the grub config for this ?
you will see bigger diffrent on bigger screens
We did a sample usb stick (h264 movie) to a 42" 1080p and it looked great.
This is a neighbour's smart tv. As far as booting to it I
haven't done and have no plans to but I imagine that could make a difference if it were a large 4k screen.
I have absolutely no plans
to buy one just to find out so it looks like you're the goto guy.
would you share the grub config for this ?
Yes. Did you want the whole thing (/boot/grug/grub.cfg) or/and just
how I generated/installed it?
If I am not mistaken it was on a
archlinux wiki that I first stumbled across a reference to it.
I'll
see if I can find it again as it proved to be very helpful. Also I
need to eventually bring this znver1 up to speed as it kickstarted
this process for me. It's default monitor is a 7" 720p. I like it
even for movies but only use the console framebuffer for that as there are no xorg apps/libs at the moment and probably will never be.
This weekend I plan to be lazy so probably later this week.
42" is just still not big screens, around 200" is :=)
yes, in gentoo its grub source file to edit is /etc/default/grub
i just like to see the penguins here if possible as your test
say it works :)
42" is just still not big screens, around 200" is :=)28" is as big as it gets here (4k).
I am thinking smaller. Offhand
10" or 12" if the right one(s) can be found. In the meantime a 4k efi boot to the 28" is my current toy on a nvme disk.
yes, in gentoo its grub source file to edit is /etc/default/grubFor graphic boots I have the below in /etc/default/grub;
GRUB_GFXMODE=auto
GRUB_GFXPAYLOAD_LINUX=keep
GRUB_TERMINAL_OUTPUT="gfxterm"
The "GRUB_GFXMODE=auto" option will detect and use the native
resolution of the monitor, currently 4k. I did try both 1080p and a
720p monitors on the same system with it successfully detecting and booting the correct resolution in time to display all the boot
penguins it can on the top line. For both 4k and 1020p all 16
penguins are displayed just like the doctor ordered.
For the record a SSD sata drive also works but it incorrectly
identifys it as hd0 when there is an nvme disk and should be hd1.
I think this might be a bios issue but have yet to find a fix other then to not use the sata interface for booting.
i just like to see the penguins here if possible as your test
say it works :)
Yes it does. For a 4k monitor I think a 12 core (two threads per
core) would look the best. :::evil grin:::
it shows no penguins here, might need more kernel boot line
options ?

more work is need for me to make it work
