Odd text behavior on Websites and others

Odd text behavior on Websites and others

[Rudolf Künzli]

Online, just now noticed some websites are coming up ok, but then
characters rapidly begin to disappear or get replaced by wrong 
characters.

If I click on any words in this post several times, the missing 
characters "Kr" intermittently appear in the example above and
disappear
 in this sentence. Also just noticed that same behavior occurs when I 
move the mouse in and out of the text pane. Very odd.

Some menus in applications (Evolution, LibreOffic, etc.) are corrupted
too, 

System was working before the updated nouveau driver.

System: Linux mephisto 4.1.3-201.fc22.i686 #1 SMP Wed Jul 29 20:53:52
UTC 2015 i686 i686 i386 GNU/Linux

Graphic Card: GeForce GTX 745

Nouveau Driver: xorg-x11-drv-nouveau-1.0.11-2.fc22.i686

What is a GTX 745? (I'm looking for a GKxxx or GMxxx model.) Are you
using glamor? What bit of "nouveau" did you update? There isn't a
single nouveau driver... (or any other GPU), it's lots of different
bits and pieces. kernel, libdrm, xf86-video-nouveau, mesa.

OK, there's no EXA support for maxwell, so you're using glamor. Before
kernel 4.1, unless you had extracted your own ctxsw firmware, you
didn't have acceleration at all, that was likely the change that
triggered the issue.

The glamor integration in nouveau is, sadly, broken. But it's unclear
whether that's the cause of your issue. You can either add

Option "NoAccel" "true"

to the device section in your xorg.conf, which will disable 2d
acceleration and bring you back to the same state you were in before,
or you can add

Driver "modesetting"

(or uninstall xf86-video-nouveau) which will use the modesetting
driver which has a non-broken glamor integration. You may still get
the same issues though, as they could just be generic
mesa-sucks-on-maxwell issues (I don't have a Maxwell GPU, no one else
has been interested in debugging/fixing issues).

Thanks - the only xorg.conf I found is -
 /usr/share/abrt/conf.d/plugins/xorg.conf
Is this the file to be edited?

No, you probably want something in /etc/X11... a lot of the time it's
split up into a bunch of separate files in like /etc/X11/xorg.conf.d
or something. You should consult your distro documentation for how to
make it happen.

Re: Odd text behavior on Websites and others

[Rudolf Künzli]

I checked for all kind of conf files in /etc/...
I can't figure out where the configuration file is placed.
I found some for keyboard configuration...
The Fedora 22 Installation Guide and the Release Notes don't reveal the
necessary informations.
I feel lost a little bit...
I look further

[Rudolf Künzli]

I don't have a file /etc/X11/xorg.conf but a folder
/etc/X11/xorg.conf.d

[rudolf@mephisto xorg.conf.d]$ ls -la /etc/X11/xorg.conf.d
total 12
drwxr-xr-x. 2 root root 4096 Aug  4 08:25 .
drwxr-xr-x. 6 root root 4096 May 27 11:40 ..
-rw-r--r--. 1 root root  265 Apr 21 17:06 00-keyboard.conf

Then a folder /usr/share/X11/xorg.conf.d with serveral config files but
I don't see which one to be edited...

[rudolf@mephisto xorg.conf.d]$ ls -la /usr/share/X11/xorg.conf.d
total 32
drwxr-xr-x. 2 root root 4096 Jul 31 18:33 .

-rw-r--r--. 1 root root  789 Jul 13 00:54 90-libinput.conf

Any other place to look for. find didn't help...

I guess I'll have to run "x config" as root to get a xorg.conf which I
can edit later...

Re: Odd text behavior on Websites and others

[Ilia Mirkin]

Add a file to /etc/X11/xorg.conf.d, named anything-you-want.conf, which contains

Section "Device"
  Driver "modesetting"
EndSection

Hopefully that should do it.

Re: Odd text behavior on Websites and others

[Rudolf Künzli]

I did as you proposed. Unfortunately my password wasn't accepted no
more. I tried the other option with Option "NoAccel" "true" with the
very same result.
It seems that these modifications will interfere some other stuff...

Just a precision. It seems that the password is accepted and the screen
turn to "black" for a second. After then it returns to the login
screen. It doesn't give a message as for a wrong password.
Sorry, I didn't give a comprehensible description.

I don't think there will be a fast fix of the problem.
I did install the NVIDIA driver. The problem disappeared.
I'd loved to stay with the nouveau driver anyway!
Thanks for your effort.

Device sections have the following format:

        Driver     "driver"
        entries
        ...

The *Identifier* *and* *Driver* entries are *required* in all Device sections.
All other entries are optional.

e.g.

Section "Device"
    Identifier "video0"
    Driver     "modesetting"
EndSection

Thank you very much.
I switched to the appropriate NVIDIA driver and the system works fine
with it.

Odd text behavior on Websites and others

[Rudolf Künzli]

Online, just now noticed some websites are coming up ok, but then
charac
ters rapidly begin to disappear or get replaced by wrong 
characters.

If I click on any words in this post several times, the missing 
characters "Kr" intermittently appear in the example above and disappear
 in this sentence. Also just noticed that same behavior occurs when I 
move the mouse in and out of the text pane. Very odd.

Some menus are corrupted too, Evolution (mail).

System was working before the updated nouveau driver.
I never installed NVIDIA drivers.

System Fedora 22 32-bits with GeForce GTX 745
