Bug Description
This affects both Ubuntu GNOME and Ubuntu Wily 20151017.1. The graphics are so badly garbled I can only file this bug on an unaffected OS where I've held back the update on just that one package to about Beta 1 status:

The tech specs show:
Internal Graphics:
• Intel ® GMA4500 onboard graphics subsystem with support for:
― Analog displays (VGA)
― Digital displays (DVI-D)
I'm just using VGA ATM.
Something else worth mentioning is this warning displayed while filing the bug report:
Your system is providing 3D via software rendering rather than hardware rendering. This is a compatibility mode which should display 3D graphics properly but the performance may be very poor. If the problem you're reporting is related to graphics performance, your real question may be why X didn't use hardware acceleration for your system.
I did try booting an earlier kernel to no avail, but holding back just this one update prevents the borkage.

I incorrectly staed above:
"The graphics are so badly garbled I can only file this bug on an unaffected OS where I've held back the update on just that one package to about Alpha 2 status"
That should have said "Beta 1 status" so I'll correct that accordingly.

How do I tell if this Lenovo M58p has the Intel GMA4500 chip?
Wily gives me fits with hashing. Can't read text even.
Xenial slightly better. Text sent out by Ubuntu is totally hashed. Text I type in on the terminal window is readable. Wallpaper and images are hashed unintelligible.
Current workaround, this is Xenial with 3.17.8031708 installed from Ubuntu Kernels:

The 4.1.0-16 is totally unusable.
Oddly uname-a reports

which doesn't seem to match ls /boot? And doesn't match the .deb:

Anyway, it works, just I'm not testing Xenial...... I've Acer and HP laptops running Wily fine. Will try Xenial on them time permitting.

This also impacts me. Screen becomes garbled quicker if Firefox is running. Screen takes a bit longer to become garbled if only Thunderbird is running.
I tried Cory's fix above, and it hasn't garbled the screen in about 45 minutes minutes with Firefox, Thunderbird, and other graphical apps running simultaneously. On my system the file /usr/share/

Under Ubuntu-Mate 15.04 only my wallpaper, scroll-sliders, and right window edges were garbled.
After do-release-upgrade to 15.10 all of the things are hashed garbled tearing whatever, even the text, even inside terminal windows.
Cory Davis (corzneffect) is correct;
Downgrading the video acceleration from "sna" to "uxa" works as a temporary fix:
#Create a config file;
sudo nano /usr/share/
#Add the following lines
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "uxa"
EndSection
#reboot

My comments on entry #13:
gedit 20-intel.conf
Copy in the lines starting with Section and ending with EndSection:
[code]
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "uxa"
EndSection
[/code]
save
quit
sudo cp 20-intel.conf /usr/share/
enter your password
Check to see if the entry made it into the directory O.K.:
cat /usr/share/
Now /usr/share/
What this configuration does is tell X11 to use the method "uxa" an older section of code, since on this pc the newer code "sna" screws up.
If this configuration doesn't work for you, then delete the 20-intel.conf entry in /usr/share/
Now Xenial and Wily install .iso's are a real bear to read on this Lenovo M58p because of the garbled text. On finish of install, before I do a reboot, I use the install ubunto to make the conf.d entry into the target ubuntu install. That's a bit tricky.
Let us know how you do.

Not surprisingly this also affects the Trusty dailies based on testing Ubuntu GNOME Trusty 20160124 amd64 since they have the Wily HWE. So the flavors participating may want to mention it in their release notes, recommending that users affected use the archived 14.04.1 images.

So I need to dig a bit deeper.
| Erick Brunzell (lbsolost) wrote : | #22 |
Lubuntu Trusty is affected to a much lesser degree so I was at least able to install it. I'm going to try the newest kernel from proposed tomorrow.
| Erick Brunzell (lbsolost) wrote : | #23 |
Looking at the 14.04.4 RC again this AM I find that the 4.2.0-29.23 kernel is OK, but this bug is present with 4.2.0-27.21. So this is apparently not so much an X bug as a kernel bug??????
AFAIK Xenial is (or at least has been) affected by this also and I'll be testing the Beta 1 candidates next week. I haven't tried testing Wily any further but it's time for me to revisit that and see if a kernel upgrade in Wily fixes the issue or not.
| Erick Brunzell (lbsolost) wrote : | #24 |
I took time to check Wily and the results are similar. This bug is present with the 4.2.0-27.30 kernel but the 4.2.0-29.31 kernel is OK.
So I'm guessing the updated intel driver fails to build properly with kernels prior to 4.2.0-29????????
| Erick Brunzell (lbsolost) wrote : | #25 |
Ubuntu Trusty 20160217 amd64 is still affected so I doubt that a fix will land for 14.04.4. That will be problematic for less advanced users affected because both the Wily and the updated Trusty images offered from the main download page(s) will fail to work.
To me the obvious simple "workaround" is to recommend using the archived 14.04.1 images that still use the 3.13 series kernel as these are not affected. The one caveat that those writing release notes and/or release announcements is when we recommend using the archived 14.04.1 images we must be certain to warn of ubiquity bug #1265192 so users don't inadvertently wipe out existing data.
| Erick Brunzell (lbsolost) wrote : | #26 |
As far as reporting upstream to move the status from incomplete back to confirmed - I have no idea what I'm doing :^(
Is this an X bug as originally thought? Or a kernel bug as now seems to be the case? I clearly can't create a new bugzilla account and file a bug report when I have no idea what I'm doing.
AFAIK incomplete bugs expire? Why should we let this expire just because I lack the tech know-how to file upstream?
| Erick Brunzell (lbsolost) wrote : | #27 |
It took a considerable amount of searching but the sna vs uxa issue does have at least two upstream bug reports:

https:/
I believe that should be sufficient. It's a known issue. I'll have to look at these newer (proposed) kernel changelogs to see if I can figure what exactly they changed.

Not fixed in 14.04.4 LTS. 14.04 originally did not have this garbled problem, but a fresh install of 14.04 does.
Should I enter a new bug against 14.04 LTS since this Xenial bug is fixed? 14.04 is supposed to be supported until 2019 I think.

@ jerrylamos, which HWE stack is in use? It mostly depends on what installation media is used (unless physical action is taken to upgrade the HWE stack):

Starting in November 2014 Ubuntu X windows screwed up with

making Wallpaper badly hashed.

Then a couple months later even Ubuntu text badly garbled, illegible.
Workarond was:
/usr/share/
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "uxa"
EndSection
So in every install since Nov. 2014 I've been making that change.
As of March 2016, that change screws up X windows and can't get desktop.
Voila, not needed, Xwindows now running fine. That took Ubuntu a year and a half to fix.
Wonder how long ubuntu Xwindows will stay fixted....

Xenial new installs have been fine lately. Putting that uxa fix in Xenial prevents X windows from running.
