[CentOS] 1600x900 not available
My laptop is a Dell XPS-13 running CentOS 7. It has a 13" 1920x1080 screen and it's a bit difficult for my mid-40s eyesight. Fedora and Debian, on this laptop, give me the option of choosing 1600x900 which is much easier for me to read but CentOS doesn't show this resolution as available. I followed the steps I found in a post on stackexchange using xrandr, substituting 1600x900 where applicable and it worked but, once I rebooted, it went back to 1920x1080 with no 1600x900 option in settings-display. Is there a way I can add 1600x900 resolution the list of available resolutions in settings-display? Thanks, Sean ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Bit of a generic answer, and not a solution, but the problem for you isn't the resolution, it is the DPI you have set, isn't there a way for you to change the DPI without losing out on the quality of the screen? ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] 1600x900 not available
I have no idea how. All I can find is the Hi-DPi settings in Gnome-Tweak but, of course, it only lets me choose to scale from "1" to "2" which makes things way too big.

You can put the xrandr command in your .xinitrc if you boot into text mode. I'm sure there's a place to put it for booting into GUI mode as well, though I'm not sure of the location. You can also play around with .Xdefaults--sometimes, setting dpi can help. For example, my yoga2 has, in .Xdefaults Xft.dpi:192 Which increases font size. -- Scott Robbins PGP keyID EB3467D6 ( 1B48 077D 66F6 9DB0 FDC2 A409 FA54 EB34 67D6 ) gpg --keyserver pgp.mit.edu --recv-keys EB3467D6 ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

If for example, your output is eDP1 then xrandr --output eDP1 --scale .8x.8 The smaller the scaling, the larger the size, so I think that .5x.5 would be what the tweak tool is offering. -- Scott Robbins PGP keyID EB3467D6 ( 1B48 077D 66F6 9DB0 FDC2 A409 FA54 EB34 67D6 ) gpg --keyserver pgp.mit.edu --recv-keys EB3467D6 ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
