Hi Kevin, Thank you for your useful suggestions. It took me several days to test and debug everything. Here are my results: 2014-04-09 10:14 GMT+04:00 Kevin Oberman <rkoberman@gmail.com>: > If you want to stay with syscon, try removing VESA from your kernel by > adding "nodevice VESA" to your kernel.

Then I tried 10-STABLE, this build: https://pub.allbsd.org/FreeBSD-snapshots/amd64-amd64/10.0-RELENG_10-r264300-JPSNAP/ Recompiled kernel to include vt and vt_vga. With acpi_video and i915kms loaded from the console, suspend/resume works. Under X, with a real Xfce4 environment: * with xfwm4 windows manager, without any compositing effects, everything works like a charm. All peripherals wake up, wifi reconnects, mplayer continues playing video, etc. * with xfwm4 and any compositing enabled, however, I got screen corruption, like this: http://i327.photobucket.com/albums/k477/ivan_rokotov_bsd/1_zps099b1f6d.png or http://i327.photobucket.com/albums/k477/ivan_rokotov_bsd/4_zps8ec8912e.png This is not a big problem, because scrolling/typing inside the window or simply moving a mouse over it solves the problem. However, I need compiz (I like Mac-style tabbing) and some GL stuff (e.g. asymptote). With compiz enabled, I get this horrible corruption: http://i327.photobucket.com/albums/k477/ivan_rokotov_bsd/2_zpsd7564e4b.png and no moving or switching to console help. No GL application starts. I also found this in the X log after resume: [ 1173.617] (EE) intel(0): Failed to submit batch buffer, expect rendering corruption: Device busy. (II) AIGLX: Suspending AIGLX clients for VT switch [ 1173.663] (WW) intel(0): drmDropMaster failed: Unknown error: -22 [ 1177.289] (II) AIGLX: Resuming AIGLX clients after VT switch [ 1177.340] (II) intel(0): EDID vendor "CMN", prod id 5239 [ 1177.340] (II) intel(0): Printing DDC gathered Modelines: [ 1177.340] (II) intel(0): Modeline "1366x768"x0.0 71.59 1366 1410 1439 1512 768 771 775 789 -hsync -vsync (47.3 kHz eP) After some experimenting, I found this patch, which solved the problem completely: http://lists.freebsd.org/pipermail/freebsd-x11/2013-October/013727.html Now, I have this in X log after resume: [ 4561.749] (WW) intel(0): retrying batchbuffer submit [ 4561.803] (WW) intel(0): retrying batchbuffer submit [ 4561.857] (WW) intel(0): retrying batchbuffer submit [ 4561.908] (WW) intel(0): retrying batchbuffer submit [ 4561.959] (WW) intel(0): retrying batchbuffer submit [ 4562.012] (WW) intel(0): retrying batchbuffer submit [ 4562.063] (WW) intel(0): retrying batchbuffer submit [ 4562.117] (WW) intel(0): retrying batchbuffer submit [ 4562.171] (WW) intel(0): retrying batchbuffer submit [ 4562.225] (WW) intel(0): retrying batchbuffer submit [ 4562.279] (WW) intel(0): retrying batchbuffer submit [ 4562.333] (WW) intel(0): retrying batchbuffer submit [ 4562.386] (WW) intel(0): retrying batchbuffer submit [ 4562.439] (WW) intel(0): retrying batchbuffer submit [ 4562.493] (WW) intel(0): retrying batchbuffer submit [ 4562.547] (WW) intel(0): retrying batchbuffer submit [ 4564.779] (II) AIGLX: Suspending AIGLX clients for VT switch [ 4564.779] (WW) intel(0): drmDropMaster failed: Unknown error: -22 [ 4565.994] (II) AIGLX: Resuming AIGLX clients after VT switch [ 4566.096] (II) intel(0): EDID vendor "CMN", prod id 5239 [ 4566.096] (II) intel(0): Printing DDC gathered Modelines: [ 4566.096] (II) intel(0): Modeline "1366x768"x0.0 71.59 1366 1410 1439 1512 768 771 775 789 -hsync -vsync (47.3 kHz eP) but everything is alive: compiz restarts correctly, GL applications work as they did before resume. Job done! A question: is this patch ok? Nothing wrong with it? Do you or anybody else experienced a similar problem and found a different solution? > I also add: > # Out : speaker + headphones > hint.hdac.0.cad0.nid25.config="as=1 seq=15" > # In : mic + external mic > hint.hdac.0.cad0.nid35.config="as=2" > hint.hdac.0.cad0.nid27.config="as=2 seq=15" While we are here...
