 |
|
Hello everybody,
since 5.6.5-gentoo I encounter many syslog lines like
| Code: | [kernel] [drm] Reducing the compressed framebuffer size. This may lead to less power savings than a non-reduced-size. Try to increase stolen memory size if available in BIOS.
- Last output repeated 4 times - |
I found the explanation at https://wiki.archlinux.org/index.php/intel_graphics#Framebuffer_compression_(enable_fbc).
But why do I get this with a i7-4790 Haswell, which is not pre-Sandy?
Anyway I followed the hint and set
| Code: | # cat /etc/modprobe.d/i915.conf
options i915 enable_fbc=0 |
After reboot the setting seems active:
| Code: | # cat /sys/module/i915/parameters/enable_fbc
0 |
But I still get the same logs. Which BIOS setting is responsible, how can I fix that?

Where can I ask about that issue? kernel.org or rather x.org?

This is definitely more related to kernel than to X. |
