Am I being punished for using onboard intel graphics?
It kinda feels that way.
Basically, I have a major problem with screen tearing on a Celeron 847, with 2GB RAM and onboard Intel Graphics that uses i915 drivers on Ubuntu 13.04 (Vanilla)
Heres wut lspci -v turns up
Tearing is most insane when the screen changes/updates images fast. I've attached a screenshot (just incase it sounds like I'm exaggerating).
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller])
Subsystem: Device 1b0a:015b
Flags: bus master, fast devsel, latency 0, IRQ 47
Memory at f7800000 (64-bit, non-prefetchable) [size=4M]
Memory at e0000000 (64-bit, prefetchable) [size=256M]
I/O ports at f000 [size=64]
Expansion ROM at <unassigned> [disabled]
Capabilities: <access denied>
Kernel driver in use: i915
I'm getting the same results with LXDE, Mint13, Ubuntu 12.10 and Openbox on the same machine. The weird thing is that occasionally Ubuntu 13.04 sometimes manages to display without tearing! But after a couple of reboots the problem seems to be back, then disappears, then it's back again ...I kid you not.
I've also tried upping the allocated RAM to the GPU but this had no effect, plus tried some compiz workarounds, but nothing seems to work.
PPPPPlease Ubuntu Pimp my onboard Intel GPU :_(
