Please commit fix for this bug as soon as possible. Because I have to login almost in 'blind' mode.
Installation was always with the lowest brightness.
I've managed to install xbacklight for increasing brightness after login. But I'll appreciate if someone writes how to fix it at login screen

Hi, I can confirm the bug. Really annoying thing, do I have to post the output on any command?

The X driver doesn't control brightness. Might be an issue in the userspace daemon. Or some ACPI quirkiness.

Possibly dupe of 872932... similar symptoms around the same time frame.

As workaround I currently use kernel option acpi_brightness
And if display goes dim after inactivity timeout brightness is not restored and stayes 0%. But this problem handles keyboard shortcuts for increasing brightness with xbacklight.

I have an HP G62 with video card Ati 5470 and I'm using the open source driver..so I think this bug doesn't affect only xorg-video-
I always have this issue while booting without AC. Tried the kernel boot option workaround but that didn't help. Have Intel gfx.

I get a complete blank screen with HP G62 on boot. Even if fiddle to get a visible screen it is restricted to 1024 x 768 so there is definitely something wrong driver installation wise. My hardware reports intel
display
bus info: pci@0000:00:02.0
width: 64 bits
clock: 33MHz
Is there Ati hardware here too? Lot's of references. Is the system getting confused between drivers?

This issue a serious issue which is still affecting users as of 20/08/12 on Ubuntu 12.04.

Bug is still present in 12.10 Beta 1. I have managed an ACPI work around but it is not satisfactory because it leads to overheating and a battery that lasts about 15 minutes! There must be thousands of these HP intel driver laptops affected.

By sheer coincidence (what are the odds?), I happen to have 2 optically identical HP G62's, one with a Intel-card and one equipped with ATI. Both suffer from the same brightness problem, very weird indeed. The remark of Ian at #10 might be correct: maybe the drivers are mixed up, in a way neither of the gfx's work.
As I happen to have both machines at the same time (they are from people who asks me to put Ubuntu on it), I can do tests on both machines, which could help in solving this bug. I'm looking forward to any suggestion. I post the exact specs later, when I have them on hand.
Santiago M. Mola (smola) wrote : | #14 |
Note that the problem is unrelated to ATI. I have access to two G62. One of them has both an integrated Intel graphics card and an ATI Radeon. The other has just the Intel card. Both suffer the same problem since Oneiric (and persisting in Precise).

Strange thing is that the model with ATI reports 2 different cards, and that in a laptop, how curious. The ATI-model differs slightly from the one smola has in #14.
I have both installed with 10.04 and they work just fine. My hope is that there is a solution before 10.04 gets obsolete (2013).

I came across a suggestion to a brightness issue on a different machine that was fixed by setting GRUB_CMDLINE_
To make the adjustment to Grub, go to a terminal, sudo gedit etc/default/grub will put the grub file into gedit, find the line and edit it and save. Then in the terminal sudo update-grub.
Not yet tried it because I need more time in case I lose my screen again! But someone else might want to.
Some more details of my set up below. (Note I currently have acpi off as part of a different more complex fix and hope to be able to get it back on to stop my laptop overheating and running the battery down in 10 minutes!)

This bugg I've enctountered since 12.04 until 13.10 they're workarounds but would be nice to be solved since it is there for a long long time.
I have encountered it on a HP 635 widh AMD 6310 integrated graphic card.

Status changed to 'Confirmed' because the bug affects multiple users.
