In the process, I've arrived at the previously attached .config (config-working.txt) that doesn't exhibit the issue, but I don't have working sound. Note that this config also doesn't exhibit <a class="bz_bug_link bz_status_NEW " title="NEW - two external screens permanently go blank on HP EliteBook Folio G1" href="show_bug.cgi?id=108462">bug 108462</a>. Now, since I was trying to _also_ make sound work (since I'm actually fairly happy to have a working .config, except it didn't have sound which is annoying), I've slowly been enabling sound options. My previously attached config-working.txt had some sound options enabled, but still no sound. Now ... with config-notbooting.txt that I just attached, I've really only changed sound configuration: +CONFIG_REGMAP_I2C=m +CONFIG_SND_HDA_EXT_CORE=m +CONFIG_SND_SOC=m +CONFIG_SND_SOC_TOPOLOGY=y +CONFIG_SND_SOC_ACPI=m +CONFIG_SND_SOC_INTEL_SST_TOPLEVEL=y +CONFIG_SND_SOC_INTEL_SST=m +CONFIG_SND_SOC_INTEL_SKYLAKE=m +CONFIG_SND_SOC_ACPI_INTEL_MATCH=m +CONFIG_SND_SOC_INTEL_MACH=y +CONFIG_SND_SOC_I2C_AND_SPI=m REGMAP_I2C got pulled in extra, apparently. Here's the weird part: this .config doesn't even boot properly. The external screens are not initialized at all, and even the internal panel doesn't get the right resolution in the fedora boot/disk password screen!! It also doesn't boot fully, I get to enter my password but it doesn't get to the display manager. Looks like I have a choice between * kernel with working graphics and no sound * kernel with flickering graphics but sound * kernel 4.13 (or perhaps 4.15?) Can anyone explain to me why selecting the sound options should have any impact on the graphics? Clearly it does though ... I can file a separate bug on that though, if you prefer.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
