[RV280] Black screen on workspace transitions

[Emmanuel Pacaud]

Binary package hint: xorg

I have desktop effects enabled, using "Desktop wall" for workspace transitions.

When I select another workspace, the desktop goes black during the transition, only showing the workspace overview OSD.

It also goes black during the transition if the "Cube" effect is selected.

Appears fixed with "radeon/r200/r300: don't clean non-emitted state" patch committed to mesa_7_7_branch and master branches.

[Swanson-ukfsn (swanson-ukfsn)]

Typical. You test it long enough to feel comfortable closing bug and problem immediately reappears.

Does it help if you disable lightning in compiz settings? (general settings)

To me it looks like DRI2 r200 has some lightning artefacts which causes wrong output colors when some lightning settings are used. (just what compiz is using it seems)

Now it would be nice to have simplier test case on what is going wrong. :)

I have rebuilt F12's latest Mesa package with this small change from git, and will test it tonight. On the machine that I originally raised this bug on.

I am running the F12 7.7-2 mesa packages with the "radeon/r200/r300: don't clean non-emitted state" fix applied "by hand".

First impressions: this patch has (so far) prevented gnome-terminals turning completely black while rotating the compiz cube. So that's good. However, the entire desktop now looks like it's been plunged into shadow while the cube rotates instead. Sometimes, that shadow can even be pink... (After waking from a DPMS "off" state, in that particular case.)

Disabling "lighting" in the compiz settings manager makes no difference.

Desktop im darkness while it rotates

Fortunately, the "lights" come back on when the cube settles again.

Screenshot oddity... (Very slow shutter-speed?)

BTW, that previous screenshot was just one in a very slow series of screenshots. This is what one of the other images turned out like!

[Rankincj-googlemail (rankincj-googlemail)]

The "dark-out" when rotating the compiz cube is still happening with the vanilla 2.6.33.1 kernel and Fedora 12's Mesa 7.7-4 packages.

radeontool can be used to assist in debugging issues where the screen blanks like this. After installing it, you run it like this:

    radeontool regmatch '*' > regdump_good.txt

    radeontool regmatch '*' > regdump_broke.txt

Run it two times. Once when you have a good, working screen (for any driver including -vesa), and once in the broken case (either from the tty console or logged into the sick box remotely).

[Emmanuel Pacaud (emmanuel-pacaud)]

There's no broken screen state in this issue. The screen goes mostly black, except for the panel and the workspace switching OSD, only during the workspace transition. After the transisition, everything works fine.

I've fixed this issue by changing a parameter in compiz configuration.

Using ccsm, the parameter is "Lighting" in the "Display settings" tab of
"General compiz options".

If I unset this boolean parameter, transitions work fine.

Probably some of the lighting/material state is not emitted in 3D driver on r1xx, r2xx with kms.

Interesting, because unsetting that parameter makes no difference here. And I even tried rebooting the PC afterwards as well.
