Hello.
After being on Ubuntu 14.1 LTS for years, I tried to update to 16.1.
Install media Would. Not. See. workstation's RAID so switched to
CentOS 7 (all my production stuff uses that anyway). Immediately
installed TDE, of course, 14.04 I think.
Two issues with Konsole, possibly related to the video driver (card is
an "AMD FirePro V4900" with their drivers).
First is that it seems to have trouble rendering the _ (underbar)
character. No problem leaving random underbars on the screen as text
advances, but can't seem to put them in the right spot. This is most
noticeable on the last line of a screen full of text.
Second, and much more annoying is that when I start Chrome (not my
primary browser but necessary for some sites), Konsole becomes
very sluggish. Not 2400-baud modem slow, but that was the first
thing I thought of. Maybe more like 9600 ... or 14.4 ...
Ideas?
I do run yum update regularly.

I recently had an experience with older ATI card - the drivers do not work
with newer kernels. Especially I tried ubuntu 16 LTS, but had to roll back
to 12. check if your card is supported in newer kernel.
As of the other issues someone might be more helpful. I am on debian.

The 1.17.2 CentOS 7 Xorg server has a built-in driver "modeset(0)" that works
for most of the big 3 gfxchips. Some distros have made the internal driver the
preferred driver for certain gfxchips. To try it can be as simple as removing
all Xorg driver packages applicable specifically to your gfxchip and restart the
server. If you have xorg.conf* configured to use a specific driver, or use an
xrandr startup script to configure Xorg, then it would need to be removed or
adjusted accordingly.

My problem is that I'm a "install it and forget it" person so I don't
have much experience poking around in xorg.conf.
AMD helpfully provides an uninstall script, which seems to have worked
but may have left some items installed (uninstall log was decidedly
unhelpful). It left me without an xorg.conf at all so the driver
picked a generic config. Problem is that I have displays on both DVI
connectors and the HDMI connector. The default doesn't see that. I
tried using aticonfig to generate an initial config but that leads to
no display and a warning about "kernel module (fglrx.ko) may be
missing or incompatible ".
Really not sure where to go from here which is why, initially, I'd
installed all the AMD/ATI stuff (including their GUI control panel).
But I can confirm that the AMD drivers aren't very good. The problem
with konsole exists when I run Opera, too, in addition to Chrome. And
I'm really tired of Firefox. :-)

aticonfig probably expects fglrx for your card and won't work with the
other drivers.

The Gentoo wiki page on multiple monitors gives some instructions on
how to hand-roll appropriate configurations if you want to go there:
https://wiki.gentoo.org/wiki/Xorg/Multiple_monitors#Configuration
Use xrandr -q to get a list of attached displays. You'll need to know
what driver your video card is using to write a valid xorg.conf for this.

In general, the Intel drivers and the nVidia proprietary drivers seem to be
the most reliable ones. The nVidia open-source drivers (nouveau) are
reverse-engineered and not very reliable at all. The AMD drivers (both sets)
are supposed to be somewhere in between. I've stuck with nVidia cards
and have had no problems (well, until the one in my laptop got end-of-lifed).
It makes sense that Opera and Chrome would react in the same way,
since they use the same rendering engine. You could try a pure Webkit
browser like Vivaldi or Midori and see if that's any better (it might not be,
though).

We lease systems and this one expires soon, actually. Next one will
have nVidia!
I played with this some more but got frustrated. Did a --force
reinstall of the AMD drivers and am back to where I was. Evidently
I've been living right or something because the issues I saw before
with Konsole being a slug when Opera was running are GONE. The
underbar artifact is gone as well. I am content not knowing why and
am just glad I have all ...
Dangit, it's back. Apparently the driver doesn't like me opening an
Opera window with GMail.
Well, regardless. nVidia next time.
Thanks, all, for all the help and suggestions!

Hi,
not sure if this can be helpful, but I noticed that if I build TDE locally within a VM
(debian) without using a clean
chroot build environment, I have similar issues with the refresh of Konsole (_ left
randomly here and there, I actually
believe they are not underbars but part of characters which is not cleared properly).
Building in the same VM but in
clean build environment does not cause this issue. The difference between the two is that
when building locally packages
are linked against the VM video driver.
All this to point out that perhaps the issue is indeed related to video card support.
Cheers

This somehow reminds me of my question about build environments. I created a
chroot build environment for debugging and testing and no such issue is
visible. Perhaps we could work out a "standard" that would be valid for
all, based on our experience.
What do you mean by clean build environment BTW?

Hi Emanoil,
by "clean build environment" I mean a chroot build environment that is
independent of what packages are installed in my
system. Basically what you get by using pbuilder or debuild.
My next thing to do in TDE is publishing building scripts for Debian/Ubuntu as I mentioned
a couple of months ago. I am
currently under very heavy work load and have had no time for TDE for a few weeks. Will
let you know when the scripts
are ready for testing ;-)

"Possibly related to the video driver" is a valid assumption :-)
Please check, if you can get the open source drivers working at a decent speed first. If
that fails, try the proprietary drivers.
