screen resolution and colour depth

Rate this Message:
Hi !
Someone had installed opensuse + freeNX on my server, but he has not finished the configuration. Now I'm having trouble with the resolution of the screen and the colour depth: Colour depth: - starting a session with pxe-boot (ThinStation, nomachine-client) on a thinClient (Igel 364LX) shows wrong colour depth. - starting a session from a "real" computer (suse 11.1 with installed nomachine-client) shows the colours correct. Screen resolution: - starting a session from a "real" computer (suse 11.1 with installed nomachine-client, everything (buttons, signs, kde-menu a.s.o.) looks very small on my 1280x1024 screen. The screen was set to vesa 1024x768 in kde-menu -> SaX2 in the session, so I tried to change it to 1280x1024, but the "test" response/break with the message "Fehler beim Testen der Konfiguration" and the var/log/xorg.99.log tells at the bottom ###### (--) RADEONHD(0): Attaching Output DAC A to Connector VGA 1 (==) RADEONHD(0): Setting UNIPHY_KLDSKP_LVTMA to incoherent (--) RADEONHD(0): Attaching Output UNIPHY_KLDSKP_LVTMA to Connector DVI-D 1 (II) RADEONHD(0): RandR: Adding RRoutput VGA_1 for Output DAC A (II) RADEONHD(0): RandR: Adding RRoutput DVI-D_1 for Output UNIPHY_KLDSKP_LVTMA (II) RADEONHD(0): Output VGA_1 using monitor section Monitor[0] (**) RADEONHD(0): Option "PreferredMode" "1280x1024" (II) RADEONHD(0): Output DVI-D_1 has no monitor section (II) RADEONHD(0): Output VGA_1 disconnected (II) RADEONHD(0): Output DVI-D_1 disconnected (WW) RADEONHD(0): No outputs definitely connected, trying again...

Thinclients can sometimes have a limited colour depth, so that might be normal unless it didn't do that before. I would suggest that the thinclient is likely the problem and needs its resolution changed since it seems everything else is working. As for the small text etc, that is a known issue and can be overcome by forcing the dpi setting of the fonts to 96 or 120 in the appearance section of your desktop environment and all menus can be resized (I know it can in kde4 at least). Also, vesa does not always support 1280x1024 mode as far as I know so that is why that didn't work. If you know the type of video card that you have, you might be better off using it in your xorg.conf file.

Booting the Igel thinclient with a live-distribution (puppy, dsl, slitaz...) shows the colour depth correct, so I think it is not limited by the thinclients hardware. > I would suggest that the thinclient > is likely the problem and needs its resolution changed since it seems > everything else is working.

Ok, I will try. But the kde-"task"-bar at the bottom is still shown as 1024 width, that looks not only like a problem with the size of the menu. It looks like wrong screen resolution, too. > Also, vesa does not always > support 1280x1024 mode as far as I know so that is why that didn't > work.

But I thought there has to be the settings for the video card in the server, not the card in the thinclient (!?)

It may not be the hardware directly, but the firmware may not be offering the mode or may not be defaulting to the right mode. You may have to change the mode on the thinclient if the firmware even detects its availablility. The KDE panel (taskbar) does not size to fit the width of the screen automatically sometimes. This is a know bug. Once you resize it to fill the screen and keep using the same mode it will remain. Unless you are physically at the server's console, its video card and colour depth settings are irrelevant. In fact, freenx will work if no graphical screen is setup on the server at all as long as the necessary programs and freenx server are installed. FreenNX doesn't use the server's resolution at all. The client defines the resolution and colour depth of the connection. With NX the rendering happens at the client's machine (thinclient) unlike VNC where the server defines the resolution and the client gets a copy of the screen. |

I'm booting a thinstation+nxclient image over pxe, so I don't know a firmware to change. Am Donnerstag, 12.

Does he get always the "highest" resolution/colours, or have I change this manually anywhere? The video graphic card of my (test-)thinClients have 8MB. Should this be enough to work with kde-sessions, firefox, openoffice .. ? Scrolling is awful, menu-items in openoffice and others are slow too. bye Olaf ________________________________________________________________ Were you helped on this list with your FreeNX problem?

Firmware = thinstation image you are booting in this case. It sounds like you're using a premade image, not one you configured yourself, so it will be using default or autodetected settings for many things. I assume thinstation has documentation for how to override these if necessary. PXES, a similar thin client, could do this with a config file on a server, or with options on the server in pxelinux.cfg passed at boot time. You could also hardcode them if you built a custom image for your hardware. > Am Donnerstag, 12.

That'll depend on resolution and colour depth, but it's lower than I've seen in a long time. What's the full specification of the client? ________________________________________________________________ Were you helped on this list with your FreeNX problem?

Performance for > nx is no problem for browsing or openoffice. I think it is not possible to change the video card, because it's an on-board- chip. I have the option to take the thinclients (I have 5 pieces) back to the seller, I think this will be the best solution. Am Donnerstag, 12.

I agree with everyone on this. I think 8MB video is awfully light for a video card nowadays even for a thinstation. Most likely that video will be somewhat choppy, but it still should work. 8MB should be enough for 1024x768 at 24bit/32bit colour. I recommend using 24bit colour if you want good colour resolution. And if you use the pxe that would operate as your firmware. Most likely the pxe image is not autodetecting your video settings correctly.
No the BIOS is different from your PXE/Firmware image. The BIOS is locked in and defines core things like video capabilities and maintains a base program. Sometimes I use the word out of context since the technology is similar.
