4k screen & Debian (Dell inspiron 7000 2015)

[fabrixx]

I tried today for the first time my new laptop screen 4K UHD and for the first time I also used Windows 8 and already hate it.

I would like in the future to put Debian Testing that I used on the old and on the Desktop.
At what point is Debian / Gnome as support to monitor 4k?

I always used Nvidia cards on Linux always finding myself very well and now I find myself for the first time to face a Radeon GPU + 4k.

Does anyone have experience with this type of monitor?
I could take advantage of the touch screen with Gnome?


Thank You.

I'd download and run a Jessie Live ISO to check out the hardware support, myself.

Tryed live of Ubuntu 15.04. System is ok but have a very small fonts & icons:

Check your DPI settings.

Which is to be expected with a hi-res screen. Luckily, it's trivial to use larger fonts and icons, just adjust that in the settings. I have no doubt Debian would have no more issues than Ubuntu.

Other elements, such as window titlebars, may also need to be adjusted, or you may need to switch to one that is adjustable. Xfce 4.12 ships with a couple of those that are larger, expressly for use with hi-res screens.

Jessie was frozen months ago, so 3.16 will never make it there.

Ok today i've tryed Ubuntu Gnome 15.04.
Gnome 3.16 is perfect size & resolution.

Firefox interface is too small but i think gtk3 browser like epiphany work well. I can try why have some network issue.
Gnome touch screen work well and is very cool touch Gnome

I not have ethernet port in this laptop and to install testing from netinstall i hope to not need to put wifi drivers during installation.

I need more tests before inserting ssd but now i know that i can put a decent & usable system.
I want try first in dualboot mode with standard disk.

[stevepusser]

You can run lspci to detect the wifi hardware, and check if it will need firmware debs on a USB stick or not--you can use the wiki or ask here; I've got them pretty much memorized by now.

I found these:

I am going to try it even if I want to wait Gnome 3:16 in Debian to make a more clean installation, maybe I'll start with the installation of Ubuntu 15:04 in a minimal partition to become familiar with the radeon drivers/DPI settings/.

[fabrixx]

Anyone have tested this non-free unofficial builds?

Maybe this helps a bit.

Ok finally i have installed Wheezy (Gnome Classic)
Now i have to setup wireless & DPI but i'm very happy

Any updates since then? Very interested on compatibility info of NVIDIA GeForce GTX 760 Ti OEM and monitor Dell P2415Q. Is it worth all the mess? My Debian value stated in signature below. If not - what 4K monitors are in Debian favor so far? I've heard of successful setting adjustment (russian wegpage)

I'm running LG 27MU67 4k monitor with GTX970 on MX-15 (jessie based) with mostly no problems. 4.2.0 kernel from backports and nvidia-driver 352.79.
You need to set Fonts to higher DPI and adjust icon sizes. Some windows need to be resized when you open them and occasional programs just don't do hidpi well at all yet.
Overall I'm extremely happy with it.

@nikobit It would be better to start a new thread if you need more advice as it is only vaguely related to the original topic.

[nikobit]

to sunrat
OK, got it. Good idea though.

Is it worth all the mess?

Definitely not.

In every Operating System in the world, for at least 2 decades, You can see the "magic" number of 96 dpi (dots per inch).
This magic number defines the number of pixels per inch which are recognizable for a human eye... and this should be the end of a story - but unfortunately it's not.

If someone will tell You that HD/UHD offers "better" visual experiance on the 17'' screen of the laptop, then either he is a moron, or You, as the customer are a moron. "True" HD works starting from 32inches and UHD starts at ~60'' - but it all depends on the distance from the screen - and in case of laptops there's simply no chance to see a difference between HD and UHD... Keep wasting Your money...

Regards.
