Firefox 38 problem

(1/4) > >>

John Poltorak:
After a lot of trial and error trying to get the latest Firefox (v38) running, I discovered the '-console' command line parameter which revealed:-


--- Quote ---Video driver is SNAP
Unable to enable DIVE

Killed by sigsegv

--- End quote ---

What should I do?

Dave Yeo:
Is that the entire output of redirecting firefox? Firefox 2>&1 | tee firefox.log
Here I get,

--- Code: ---DIVE is disabled - Panorama's shadow-buffer is enabled
Assertion failed: fcCacheChains[i] == NULL, file fccache.c, line 533

Killed by SIGABRT
pid=0x007d ppid=0x0021 tid=0x0001 slot=0x0102 pri=0x0200 mc=0x0001 ps=0x0017

--- End code ---

Note that the sigabrt comes from fontconfig.
Snap should automatically enable DIVE if it passes an sanity check, including using 32 bit colour.

Daniel Carroll:
Now that's interesting... so I typed in
Firefox 2>&1 | tee firefox.log
While running Firefox 31.8.0 in 16 million colors and 1920 x 1080 at 60 Hz, ATI Radeon X850 series using SNAP.
And got..

VMI_CMD_SETPTR - rc= 0  ulStatus= 1
Video driver is SNAP - mouse ptr will not be hidden
_init_dive:  _load_dive() succeeded
_init_dive:  hDive= 1  scrn= 0x2a50000  format= BGR4
Changing DIVE from enabled to disabled - 'layers.acceleration.disabled' is TRUE


Isn't BGR4 a four bits per pixel mode?

Daniel Carroll:
Ok, it's a 4 bytes per pixel mode. I still don't have a clue why it disables Dive. But that's normal enough.

Dave Yeo:
You have it disabled for some reason,

--- Quote ---Changing DIVE from enabled to disabled - 'layers.acceleration.disabled' is TRUE

Go into about:config, search for layers.acceleration.disabled, right click on it and choose toggle.
