I assume 2.6.23-rc6 was a typo. I marked it as a regression. Jesse, you broke henk's computer :) Sigh. Fix one 6510, break another. I've really got to get one of these machines... This machine gives me some headaches too. If you want me to test some patches or if you need more information, please let me know. Dupe of https://bugs.freedesktop.org/show_bug.cgi?id=29278 *** This bug has been marked as a duplicate of bug 1 *** *** Bug 16514 has been marked as a duplicate of this bug. *** Reverting the aforementioned commit also helps on my Dell latitude E6410 (Core i7 620M with integrated graphics controller [8086:0046]). I didn't have any problem like this one with all kernels I previously tried (up to 2.6.35-rc4). Today, I switched to drm-core-next to get VGA to work (see https://bugs.freedesktop.org/show_bug.cgi?id=29005), got the aforementioned blank screen, and fixed it by reverting the above patch. |
On my Dell E6510 I get a black screen as soon as the i915 KMS module is loaded. Kernel 2.6.23-rc6 did not have this problem. After some investigation, I found out that this patch introduced the problem: diff --git a/drivers/gpu/drm/i915/intel_dp.c b/drivers/gpu/drm/i915/intel_dp.c index 5d42661..5dde80f 100644 (file) --- a/drivers/gpu/drm/i915/intel_dp.c +++ b/drivers/gpu/drm/i915/intel_dp.c @@ -798,7 +798,7 @@ intel_dp_dpms(struct drm_encoder *encoder, int mode) intel_dp_link_down(intel_encoder, dp_priv->DP); if (IS_eDP(intel_encoder)) { ironlake_edp_backlight_off(dev); - ironlake_edp_backlight_off(dev); + ironlake_edp_panel_off(dev); } } } else {
