Setting up RH7.3 on n610c

RobertHarle — Tue, 18 Mar 2003 10:26:18 GMT

Hi all,

I have a clean install of RH7.3 on my n610c. Can anyone give me some pointers on the things I need to do to get this all running optimally? As expected, the out-of-the-box power management doesn't seem to work. With this exception, everything else is working, but I suspect not optimally!

TIA for any suggestions.

Maybe this helps? It has a workaround for the problem where keyboard/mouse freezes when screenblanking is activated when running on battery.

What exact issues are you seeing btw?

Yes, I'd seen that link.

I don't see that particular problem though. :-(

What I do see is:

i) Closing the lid does not switch the screen off

ii) It will not come back from standby

:-(

hi,
not sure abt the power management.

but the best thing in optimizing is

1. dont run any service which u dont need.
2. try re-compiling ur kernel to suit ur requirements. those which are not necessary always should go in as modules.
3. and if u want more, u can start compiling ur applications with optimization flags for gcc (guess this is not very much required.)
4. use hdparm to tune ur hdd performance. (have heard that this enhances the performance by around 3-4 times but never got it successful for me.)

just some thoughts. but have a backup before touching anything. u have been warned.

Most newer notebooks use ACPI instead of APM for power management. However, the default kernels for Red Hat 8.0 and lower only support APM. So basically you have to build a newer kernel with ACPI enabled (and usually APM disabled) in order to get power management. In addition, there are a few other quirks you need to know about.

1) ACPI is new technology, and not everything is yet fully supported under Linux.

2) ACPI is mediated through the bios but not yet standardized in the bios. Therefore /proc/acpi directory and file names tend to vary depending on maker, model, release version, etc.

3) Software suspend isn't fully implemented in Linux kernels. Some forms of suspend work, some don't, and some only work on certain hardware.

Most notebook owners use kernel patches from the ACPI project and/or the software suspend project at source forge.

I suggest you look at

to get some ideas what you can expect for the N610C or related models.
