Hi everyone, On CentOS 7 I'm running into an issue with the latest nvidia driver from elrepo: kmod-nvidia-384.98-1.el7_4.elrepo.x86_64 This driver version seem to introduce issue in detecting video modes when a monitor is connected using DVI. As soon as the machine attempts to start X, nothing happens and the monitor goes into sleep mode reporting that it has 'no signal'. It is

I asked on the Gentoo forums, and surprisingly haven't gotten an answer. When I run xrandr, I get this output: Code: Screen 0: minimum 2960 x 1050, current 2960 x 1050, maximum 2960 x 1050 default connected 2960x1050+0+0 0mm x 0mm 2960x1050 50.0* I'm using TwinView with a 1680x1050 monitor and a 1280x1024 monitor. And I want to set up some different modes in xrandr. When

I've been working on this issue for quite a while. Back in January of 2015 I posted about how well external monitors worked with the out-of-the-box CentOS 7 ATI radeon drivers and my Dell M6500 with an ATI FirePro M7820. At the time the support was seamless and 'Just Worked' without any issue. A few months later, some update came down the pipe and this broke completely, with the

While the way we find the associated connector for an encoder is just fine for legacy modesetting, it's not correct for nv50+ since that uses atomic modesetting. For reference, see the drm_encoder kdocs. Fix this by removing nouveau_encoder_connector_get(), and replacing it with nv04_encoder_get_connector(), nv50_outp_get_old_connector(), and nv50_outp_get_new_connector(). v2: * Don't

Recent qemu (latest master branch, upcoming 3.1 release) got support for EDID data. This patch adds guest driver support. EDID support in qemu is not (yet) enabled by default, so please use 'qemu -device VGA,edid=on' for testing.

Some notebook computer systems expose the EDID for the internal panel via the ACPI _DDC method. On some systems this is because the panel does not populate the hardware DDC lines, and on some systems with dynamic display muxes, _DDC is implemented to allow the internal panel's EDID to be read at any time, regardless of how the mux is switched. The _DDC method can be implemented for each

Fall back to retrieving the EDID via the ACPI _DDC method, when present for notebook internal panels, when retrieving BIOS-embedded EDIDs.

Check header before trying to read the complete edid blob, to avoid the log being spammed in case qemu has no edid support (old qemu or edid support turned off).
