If it is to just get better font rendering (infinality freetype rendering); have a look at this gist: https://gist.github.com/sunnz/11cd72135a0d6a3ec6b6 it requires the installation of some packages from non fedault repos such as nux-desktop and sets up a new fonts.conf file. However, once used, it is impossible to work on a RHEL 7 type system without this installed. Font rendering looks better than Windows and Ubuntu. -----Original Message----- From: CentOS <centos-bounces at centos.org> On Behalf Of Pete Biggs Sent: Thursday, 12 July 2018 10:51 To: centos at centos.org Subject: Re: [CentOS] bad text under KDE and C7> > > > Kernel driver in use: i915 > > Kernel modules: i915 >The i915 driver is fairly rock solid - virtually all desktop machines these days have on-board Intel video, it's the lowest common denominator.

Xorg.0.log uses the phrase "falling back" a few times. I expect that just means I've not inerfered with defaults. boot.log-20180625 does not contain any of the sequences rap, RAP, ideo, IDEO. dmesg contains graphics and video, but nothing that seems interesting.> For some reason you say you disliked Gnome - but does Gnome show issues > (they use the same video driver)?I'll try it.> A long shot is the theme.

(This is just to make sure there's no hardware problem.)Only as a last resort. Having already lost a couple graphics cards (not in this machine), I open the case rarely and with fear and trepidation. When I hover over text, the black tape effect goes away. Do graphics cards know about text or hovering? -- Michael hennebry at web.cs.ndsu.NoDak.edu "Sorry but your password must contain an uppercase letter, a number, a haiku, a gang sign, a heiroglyph, and the blood of a virgin." -- someeecards

One of them, I think it was gnome-classic, did videos badly. It was a bit like a shutter came about a quarter way down at about once per second.

But hardware issues may affect the rendering of some things. P.

It may be that your particular combination of chipset and driver is manifesting a bug - or it might be bad hardware. Try booting a live distro - such as Fedora (other distros are available). It won't affect your installed data, but it will provide a different driver to try. P.

Apparently logging out and in again fixed or obscured the problem.> One of them, I think it was gnome-classic, > did videos badly. > It was a bit like a shutter came about a > quarter way down at about once per second.I'll try the live CD suggested elsewhere.> Late for work.Again. -- Michael hennebry at web.cs.ndsu.NoDak.edu "Sorry but your password must contain an uppercase letter, a number, a haiku, a gang sign, a heiroglyph, and the blood of a virgin." -- someeecards
