Description Chris Ricker 2002-12-29 09:17:08 EST
I have a laptop which uses the trident cyberblade chipset, and which only works at 1024x768. In the past few releases of RHL, I've only been able to install by either using: * text mode * forcing the resolution to 1024x768 With beta3, I started an NFS install and forgot to force the resolution. When anaconda started X, the screen went black (since anaconda tries to run at 800x600?), just as with older releases.... However, with beta3 if I switch to a text VC, and then back to X, then anaconda displays This seems to suggest that anaconda should Just Work on this machine in graphical mode w/o having to force resolutions?

Most likely an X server issue.
Comment 2 Chris Ricker 2003-01-24 01:21:57 EST
Saw the same thing with beta4 started install X started screen went black switched to VC 1 switched back to VC 7 screen then magically worked
Comment 3 Mike A. Harris 2003-01-26 05:04:45 EST
Attach X server log, config as per usual. TIA
Comment 4 Chris Ricker 2003-01-26 10:16:08 EST
You want it from during install, or from the working system after install?
Comment 5 Mike A. Harris 2003-01-26 17:36:17 EST
After install.. The installer tries to use the same thing that will be used on the installed system, but if it fails, it falls back if possible to an alternate driver. Failures in these cases generally indicate our default driver might not be the best one. Also testing on an installed system is much simpler to reproduce. Problems that occur _only_ in the installer and not at runtime are very difficult to debug, and very time consuming. Trident support is sort of tapering off upstream as maintainers do less volunteer work on older drivers and start to focus on contractual driver work. ;o/ We'll see what we can do though. TIA

Comment 8 Chris Ricker 2003-01-28 01:04:45 EST
Attached log and config from beta4 on that machine That machine has an LCD which only works at 1024x768 (if you run it at, say, 800x600, it displays as an 800x600 window with a 1024x768 border around it)
Comment 9 Chris Ricker 2003-02-10 10:27:07 EST
Same deal with pre-beta5
Comment 10 Mike A. Harris 2003-02-10 13:36:58 EST
The trident driver doesn't seem to be too actively maintained upstream nowadays for all chips that it supports. Unfortunately, without an upstream fix, this probably wont change for our final release as I don't have any Trident video hardware nor technical specifications and Trident wont supply either.
Comment 11 Mike A. Harris 2003-02-14 02:37:49 EST
Would it be prefered to have the 'vesa' driver be the default for this chip instead? That way multiple resolutions might work perhaps. Please test it, and let me know if that is considered a superior default.
Comment 12 Chris Ricker 2003-02-14 11:07:38 EST
The chip actually supports multiple resolutions -- it's the LCD which is resolution-locked. Right? If I configure it at, say, 800x600, what I see is (warning: bad ASCII art ;-) ------------------------------------------------ | | | ------------------------------ | | | | | | | | | | | | | | ------------------------------ | | | ------------------------------------------------- where the inner box is an 800x600 image (my X desktop) the outer box is 1024x768, and the border between the two is solid black At any rate, I'll try VESA and see....
Comment 13 Mike A. Harris 2003-02-14 12:20:42 EST
You do realize that an LCD display has physically fixed size pixels on the screen that are not changeable in size right? Every LCD display has a native video resolution, and only runs truely in that one resolution. Any other resolution gets either centered on the display, or gets hardware scaled to fit the true resolution of the display. So no matter what, you are using the native resolution of the display at all times. Wether or not the Trident video hardware you have can do hardware scaling, I have no idea, as I don't have Trident's hardware documentation. Basically there is one of 3 possible scenarios for this problem report: 1) Your hardware doesn't support scaling (unlikely IMHO) - In this case, there is nothing you or anyone can do 2) Your hardware supports scaling, but the video driver does not - This would be an unimplemented feature and not a bug. Someone with the video hardware, and the specifications for the hardware would have to write support for this. I don't have the docs or hardware, so it wouldn't be me. ;o) Probably Alan Hourihane, the driver maintainer. 3) Your hardware supports scaling, and the driver does too, but it is broken for some reason on your chipset currently: - This would require someone who has the hardware to debug the issue, with the hardware right in front of them, and most likely they would need the Trident hardware datasheets in order to look up registers and programming information. I don't have the docs or hardware, so it wouldn't be me. ;o) Probably Alan Hourihane, the driver maintainer. If the vesa driver does work, and you consider it a better solution, I will change: (II) PCI: 01:00:0: chip 1023,8420 card 0e11,b15a rev 5d class 03,00,00 hdr 00 to use the 'vesa' driver. Other than that, unfortunately there is not much I can do other than hope Alan fixes it, or implements the missing feature.
Comment 14 Chris Ricker 2003-02-19 23:01:56 EST
the vesa driver doesn't seem any better it still does the 800x600 screen centered in the middle of a fixed 1024x768 display, and it has weird graphical artifacts all over the place for now the best solution seems to be flipping to VC 1 and then back to X in anaconda to defreak X with the trident driver
Comment 15 Chris Ricker 2003-10-17 17:34:06 EDT
closing, since I no longer have the hardware
