I tried that, but it still flickers. pavel@half:~/misc/fgfs$ cat /proc/cmdline BOOT_IMAGE=(hd0,2)/l/linux/arch/x86/boot/bzImage root=/dev/sda4 resume=/dev/sda1 radeon.dpm=0 > Power consumption would be totally awkward, but it should help nailing down > the problem. It seems chromium makes the flicker way worse.. even when running on different virtual desktop. I'm not sure which sysfs settings I should tweak (or if I should be tweaking them with .dpm=0). But sysfs says: pavel@half:/sys/bus/pci/drivers/radeon/0000:01:00.0$ ls backlight drm irq resource boot_vga enable local_cpulist resource0 broken_parity_status firmware_node local_cpus resource0_wc class graphics modalias resource1 config i2c-0 msi_bus resource2 consistent_dma_mask_bits i2c-1 power rom d3cold_allowed i2c-2 power_method subsystem device i2c-3 power_profile subsystem_device dma_mask_bits i2c-4 remove subsystem_vendor driver i2c-5 rescan uevent driver_override i2c-6 reset vendor pavel@half:/sys/bus/pci/drivers/radeon/0000:01:00.0$ grep . * grep: backlight: Is a directory boot_vga:1 broken_parity_status:0 class:0x030000 Binary file config matches consistent_dma_mask_bits:40 d3cold_allowed:1 device:0x9553 dma_mask_bits:40 grep: driver: Is a directory driver_override:(null) grep: drm: Is a directory enable:1 grep: firmware_node: Is a directory grep: graphics: Is a directory grep: i2c-0: Is a directory grep: i2c-1: Is a directory grep: i2c-2: Is a directory grep: i2c-3: Is a directory grep: i2c-4: Is a directory grep: i2c-5: Is a directory grep: i2c-6: Is a directory irq:16 local_cpulist:0-3 local_cpus:f modalias:pci:v00001002d00009553sv00001025sd00000212bc03sc00i00 msi_bus:1 grep: power: Is a directory power_method:profile power_profile:default grep: remove: Permission denied grep: rescan: Permission denied grep: reset: Permission denied resource:0x00000000c0000000 0x00000000cfffffff 0x0000000000042208 resource:0x0000000000005000 0x00000000000050ff 0x0000000000040101 resource:0x00000000d6200000 0x00000000d620ffff 0x0000000000040200 resource:0x0000000000000000 0x0000000000000000 0x0000000000000000 resource:0x0000000000000000 0x0000000000000000 0x0000000000000000 resource:0x0000000000000000 0x0000000000000000 0x0000000000000000 resource:0x00000000d6220000 0x00000000d623ffff 0x0000000000046202 grep: resource0: Permission denied grep: resource0_wc: Permission denied grep: resource1: Permission denied grep: resource2: Permission denied grep: rom: Permission denied grep: subsystem: Is a directory subsystem_device:0x0212 subsystem_vendor:0x1025 uevent:DRIVER=radeon uevent:PCI_CLASS=30000 uevent:PCI_ID=1002:9553 uevent:PCI_SUBSYS_ID=1025:0212 uevent:PCI_SLOT_NAME=0000:01:00.0 uevent:MODALIAS=pci:v00001002d00009553sv00001025sd00000212bc03sc00i00 vendor:0x1002 Thanks, Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
