I installed C7 along with MATE desktop... My monitor is a 4K unit but when I goto the System -> preferences -> hardware -> Displays there is selection for the 4K display. It stops at 1920x1080. The var log x file shows the 4K resolutions in the file so that is good. How do I get the selections for 4K to show up? Thanks, Jerry

...machine and installed Xubuntu and I'm still figuring things out. I'm interested in working with The Linux Frame Buffer. Many years ago, I started a project called ezfb and I would like to continue developing it on a machine capable of 4K. Is it possible to have a frame buffer that does 3840x2160 ? With nouveau installed as my video driver, I can get to a frame buffer console of 1920x1080, but I am limited to that resolution in Xfce as well. With a proprietary nVidia driver installed I can get to 4K in Xfce, but my frame buffer is 640x480, 4 bit color. When I try fbset to change anythi...

...HDMI cable to a 65 inch Samsung curved screen LCD 4K monitor. I'm not sure what I am looking for in dmesg and xorg log. Please advise. I have built the 3.19.8 kernel and enabled frame buffer support. I can see 7 out of the 8 penguins when I boot. My ultimate goal is to be able to boot to a 3840x2160 32 bit (frame buffer) console. Then go into Xfce, or not, as needed. I like to write frame buffer apps that run in the console. Thank you.

Thanks - I suspected it was too new. I'm finding the monitor capabilities miss identified even if I use an older card - I'm

I got 1920x1200 at 59.95Hz via DVI and 3840x2160 at 60.00Hz via HDMI at the same time with the proprietary nvidia driver. I get flickering on the 1920x1200 at 59.95 with the nouveau driver (it doesn't flicker if I lower it to 1920x1080 at 59.96). Any idea why? proprietary: $ xrandr Screen 0: minimum 8 x 8, current 5760 x 2160, maximum 32...

I think I may have updated the tv firmware between when it worked and when it didn't. I wonder it it has to do with bit depth. I use lubuntu and it doesn't let me pick the bit depth so I don't know what it using.

I have a Gigabyte GeForce 1050 connected by DVI to a monitor (1920x1200 resolution @ 59.9502 Hz) and a TV via HDMI (3840x2160 @30 Hz). The problem is the TV used to work at 59.9685 Hz but then it started showing "No signal" on the TV. I was changing settings trying to get it to work again and I happened to change it to 30Hz and it worked. The specs are here: https://www.gigabyte.com/Graphics-Card/GV-N1050OC-2...

...table pointed to by the 'T' table, but we have a counterexample to that). Could you suggest a way to find this information either from the VBIOS or based on the GPU? Are there differences between regular HDMI and DP -> HDMI (passive)? This is becoming more and more relevant as 2560x1440/3840x2160 displays are become more common, while (dual-link) DVI-D is on its way out. Thanks, -ilia
