Sigh - Iam not awake yet. I meant "refresh rates" where I said "resolution" above. Sorry about that. Now that I am at it, the best resolution (Yes, I do mean resolution) to run a Nokia 447Za under is 1152x864, not 1024x768 as is default. (It maximizes screen area under acceptable refresh rate; I saw this recommened in reviews of the monitor, and I agree). MVH -Thue Are you sure? Looking around on the web, I've found some differing data. On page 3 of http://sara.kgcomputer.com/documents/monitors/GA771.pdf, it says that the Nokia 447Za does Horizontal 31-71 kHz and Vertical 50-120. Then, on http://press.nokia.com/PR/199707/778221_5.html, it says the 447Za, "is capable of a maximum refresh rate of 120 Hz, and has a horizontal frequency range from 31 to 72 kHz." Then, on http://press.nokia.com/PR/199903/777132_5.html, it says, "Top horizontal frequencies range from the Nokia 447ZA's 86 kHz" So I don't know what to believe. As root, try running '/usr/sbin/ddcprobe' and see if the monitor returns the refresh rates from the firmware. I can't find my manual right now, but those values I wrote was what it said. Running ddcprobe supports rh's values: --------------------- [root@kg31 thue]# /usr/sbin/ddcprobe Videocard DDC probe results Description: Intel Corporation Intel(R) 815 Chipset Memory (MB): 1 Monitor DDC probe results ID: NOK00ba Name: Nokia 447Za Horizontal Sync (kHZ): 30-72 Vertical Sync (HZ) : 50-120 Width (mm): 300 Height(mm): 230 --------------------- (note that the first link you gave was to another monitor model) I think I have to retract the claim that the rates setup caused X to fail. I tried installing the new rh beta, and even though it was configured with the same rates X works fine. I don't know why X failed to work when I installed RH9, and I don't know why reconfiguring fixed it. I just assumed that since those values were at odds with my manual (and chosing them differently in reconfigure made X work) that they were at fault. Ok, well, the vaules that the firmware returned (50.0-72.0) and (50.0--120.0) exactly match what we have in the MonitorsDB file, so I think we should leave the refresh rates alone. I'm going to close as "Rawhide" since the problem does not appear in the Fedora beta. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030827 Debian/1.4-3 Description of problem: The default monitor resolution for my Nokia 447Za chosen during installation is way off. Bad enough that X wouldn't run before I corrected the resolution. It does detect the monitor correctly. These are the correct values, taken from my monitor manual: HorizSync 31-68 VertRefresh 60-85 Version-Release number of selected component (if applicable): (the one that came with RH9) How reproducible: Always Steps to Reproduce: 1. Reconfigure X with a Nokia 447Za monitor 2. ... 3. Profit! (You must have heard that joke before...) Additional info:
