Description of problem: When resuming from suspend-to-ram on a Toshiba Portege R200 the brightness is set very low. Looking in /proc/acpi/toshiba/lcd shows the same brighness level as before suspending so preservation of the brightness level would seem to work but has no effect. Any attempt to raise or lower the brightness using echo "brightness: <value>" > /proc/acpi/toshiba/lcd has no effect after a resume. Adjusting brightness works as expected before a suspend. Version-Release number of selected component (if applicable): 2.6.18-8.1.1.el5 How reproducible: 100% Steps to Reproduce: 1. Press Fn-F3 or run pm-suspend 2. Press powerbutton to resume Actual results: Actual brightness is set very low even though /proc/acpi/toshiba/lcd shows the same values as before suspending. Expected results: Actual brightness reflects the value of /proc/acpi/toshiba/lcd instead of being very low. Additional info: R200 has the i915 chipset.
Doesn't appear to be a generic i915 chipset issue. I've borrowed a laptop from jmoyer here (which has the i915) and the display works after suspend-to-ram. I'll try to hunt down a toshiba laptop ... P.
I'm closing this BZ out as CANTFIX. We do not have HW to test with.
