Re: Dim video on a G3

A long time ago I rebooted an iBook running OS X and started GNU/Linux (YDL 2.something). The screen was dimmed and the volume was turned down when I rebooted. These settings were stored in the PRAM and persisted as the max values for brightness and volume in my Linux session. It took a long time for me to realise what the problem was.

Anyway, if you're using BootX then you must have some version of MacOS installed (I think). Try booting MacOS and check the display settings there.

Does the monitor by chance have a brightness control? I could tell you a funny story about a guy, a new sound card, the sound drivers, two weeks of kernel recompilations and head scratching and the volume control on the external speakers. Really funny story.

Good luck.

        I have an Apple Power Macintosh G3 desktop 233 MHz, it is
running Debian testing (basically).  It boots with BootX.

        Attached to it is an Apple Multiple Scan 720 Display.

        Some days ago my wife was with our eleven-months son in her
lap, and while she was distracted he banged furiously at the keyboard. The
screen went dim, we can hardly see anything.

        A friend just tried setting the flyback, he got the screen
brighter but without any contrast... so I am guessing it is either a
hardware problem about the signal strength, or (more probably) my son
activated some OpenFirmware magic combination.

        Any ideas?  Am I doomed to go to Apple repair?
