I blacklisted the i2c-piix4 module, which I think I don't have and was giving this warning:
ACPI: resource piix4_smbus [io 0x0b00-0x0b07] conflicts with ACPI region SMBX [io 0xb00-0xb0f] as I thought it might be related, but nothing changed. I am uninstalling radeontool to ensure it is not (tried to be) used by either pm-utils (which suggests it) or acpi-support (which recommends it). They use it this way: $ dpkg-query -L pm-utils | xargs grep radeontool /usr/lib/pm-utils/module.d/uswsusp: radeon-off) OPTS="$OPTS --radeontool" ;; /usr/lib/pm-utils/sleep.d/99video:if command_exists radeontool; then /usr/lib/pm-utils/sleep.d/99video: radeon() { radeontool "$@"; } /usr/lib/pm-utils/sleep.d/99video: radeon() { echo "radeontool not found" 1>&2; return 1; } This is related with "quirks" and needs to be called for explicitly $ dpkg-query -L acpi-support | xargs grep radeontool /etc/acpi/lid.sh: [ -x /usr/sbin/radeontool ] && radeontool light on /usr/share/acpi-support/screenblank: [ -x /usr/sbin/radeontool ] && radeontool light off It needs to be configured in /etc/default/acpi-support, which is not done here. The reason I went looking into this is that I had all sort of instabilities on boot, suspend/hibernate and restore from hibernate, which seems that I managed to solve by removing the "nosplash" option to the kernel (it caused non-functional screen about 30% of the boots) and adding "i8042.nomux=1 i8042.reset" (was causing no keyboard-trackpad about 50% of boots) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1049101 Title: Radeon tool does not work with a Radeon HD 6320 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1049101/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
