Toshiba 1905-s301 and XFree Refresh Rates

[jrjuiliano]

Hi all,

I have a Toshiba 1905-s301 laptop, with a 15 TFT screen and an ATI Radeon Mobility M6 video card.

Trying to find information on refresh rates to use in Xfree86. I'm using Gentoo and the automatic configuration doesn't like to play nice with these video cards.

Checking Toshiba's web site they only give rates for EXTERNAL monitor connections...

If anyone has some good working refresh rate settings (horizontal and vertical) let me know!

Thanks in advance... J.R. Juiliano

Hi,

With a little bit of luck, you'll find a laptop with same graphic card / screen at

Hi J.R.

I also have a 1905-S301 running Linux (RH 7.3) and XWindows. Here are some details from my /etc/X11/XF86Config file:

HorizSync 31.5-48.5
VertRefresh 50-70

Also my timings for the 1024x768 mode:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
# --- 1024x768 ---
# 1024x768 @ 60 Hz, 48.4 kHz hsync
Modeline "1024x768" 65 1024 1032 1176 1344
768 771 777 806 -hsync -vsync

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Sometimes X comes up in a jittery, out of sync mode, and if I restart it usually comes up fine the second time, perhaps some tweeking of the above timings will help. This is not a serious problem.

Overall, I am VERY happy with this laptop, I have the CD burner, DVD, network, audio, and pointer all working in Linux. The screen looks fantastic in X and KDE3. I would like to get power management working under linux. Any tips/hints?

I use this machine for software development, the 2 Gig processor really speeds up compile times.

A quick tip for the DVD, most documentation for DVD players tell you to link /dev/dvd to /dev/hdc, however the Redhat install detects the CD burner, and sets it up as a SCSI device (cdrecord requires this) /dev/scd0. So to get the dvd software to work you need to link /dev/dvd to /dev/scd0. (not /dev/hdc)

Good Luck,

Phil Brooks

Hi,

I've been running about the same refresh rates. I don't have the timings placed in there (which may help), but I did add this to mine:

Section "DRI"
Mode 0666
EndSection

I'm running Gentoo 1.4_rc2 right now, and I also have that problem with the jittery screen on occasion, but it works if I restart X when that happens.

As far as power management goes, I think it's still not developed completely. I'm running kernel version 4.2.20 and made sure to enable ACPI options including button, etc, and then to only put in APM generically (no options underneath it) when compiling the kernel. It can change a bit when pulling the plug and running on battery, so I know it's aware of the changes, but it's still a bit clueless as to battery state.

As far as the DVD or CDRW is concerned, I haven't had a chance to play with it (since I dual boot with Win 2k and use that to make it work), but as I understand it you need to use SCSI Emulation, and then pass SCSI options to GRUB at boot time.

It is a great laptop, even with the ATI card on it, and so far I'm enjoying it all very much. I plan on using mine to some network testing, as well as using OpenOffice, etc., for documentation. I've also compiled in nessus, nmap, ethereal, and am trying to get Nagios configured (what a pain).

Anyway, thanks for posting!
