Re: Monitor problem
Hi Dave, The Wassermans wrote: I have recently switched to Ubuntu 8.04. Am a new convert still trying to configure my computer. =) At issue is my Samsung SyncMaster 205bw (lcd) monitor. is the 15 pin VGA or DVI connector in use? I have noticed that my photographs and videos are appreciably fuzzier than they are using the same monitor in XP. I am presuming that it must be something to do with the Driver? What is the application that you are using to view or edit the images? Is there smoothing or zooming or image compression going on here you haven't seen? What is the file format? How big is the image in kilobytes? How big is the image in pixels? Fuzzy is such a loose word to use here, as the application you use in windows may actually be doing smoothing without you knowing... Sumsung do not provide a Linux driver as such. Questions: * Where in Ubuntu do I go to look at what driver is actually in use? The driver in Ubuntus case is actually the video card driver... * Are there alternative drivers for my monitor? Linux and xorg doesn't do monitor 'drivers' as such ... * Is there a solution to improving the quality of rendering? The windows 'driver' is mainly to give hints to the video card about which screen resolutions to run, which are native and what gamma modes and colour correction is supported. Mainly so the user doesn't need to fiddle with them. Most of these options in Linux/xorg are configurable, however I'm not sure if these are changeable from the GUI. regards, Kim -- Operating Systems, Services and Operations Information Technology Services, The University of Adelaide [EMAIL PROTECTED] -- ubuntu-au mailing list ubuntu-au@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-au
Re: Linux Servers for Infrastructure
Null Ack wrote: Im reflecting on a infrastructure project I did recently and how this might have been done using Linux servers (Ubuntu). In this example the desktops have to remain the approved XP SOE. To give an outline of the environment: * 1450 desktops running Windows XP on a SOE in three buildings separated via fibre connections You mean your WAN/internet connectivity by 'fibre' ? * Beyond the SOE applications are packaged into MSI's and controlled via group policy A single decent terminal server with apps managed in one location. Linux desktop with rDesktop clients... * AD is used throughout use LDAP/802.1X/Radius/DHCP/Dynamic DNS ; see below The services for the servers are: * File serving over the fibre connection to the large replicated SANs (there is two) that stores all data We use Samba sharing via CIFS connected via SAN to our Arrays. Last count we're exporting 20TB in different file systems to thousands of users. * Authentication You can use LDAP(OpenLDAP or Fedora Directory Server), with Radius (FreeRadius) connecting back via PAM on linux servers and desktops. * Software distribution for patches and MSI packages to be installed into the desktops as allowed by group policy hmmm windows desktop land ... no idea. * DNS Bind 9.3 * Mail Exim 4 or Sendmail 9.* * NTP ISC NTPd * Intranet and Internet web serving Apache 2, what ever apps you had in mind, your CMS could be Zope 3 or any number of other CMS tools, there are too many to mention. * Print serving Samba + CUPS + ((pykota + ldap or mysql ) for print quota) * Monitoring and alert system Nagios or Groundwork * Single sign on LDAP + PAM * Security auditing of desktops Two eight way servers (for scalability) were depoyed in seperate physical locations and setup in a cluster for all services to allow for online maintenance of one node. The servers had no internal storage and they booted off a LUN in the SAN. Only two? We do similar SAN boot from Blades. Im not sure about the software distribution aspetcs and group policy? You could run Ubuntu server, or Centos if you were averse to paying for you linux distro or go the whole hog and do the Redhat thing and get support. We have ~150 Redhat servers and use Satellite to roll out updates/security/patches/config Im curious about this. What I see happening is Linux being used for app / web / DB servers but not alot in infrastructure for desktops - maybe it just the places Ive worked at. Linux excels at internet facing services. It is creeping into the desktop space. We've deployed 250 Redhat desktops in the last year and then the server infrastructure to support them. Thoughts? many ... where do you want to start ;) cheers, Kim -- Operating Systems, Services and Operations Information Technology Services, The University of Adelaide [EMAIL PROTECTED] -- ubuntu-au mailing list ubuntu-au@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-au
Re: multi soundcards
Hi Norm, Norm wrote: Xubuntu 7.10 on an Intel SE440BX-2 mobo, PIII 500 CPU, 384M of ram. I want to run 2 sound cards to run 2 ham radio applications, Xastir and FBB. Sound cards are ESS Solo-1 and Creative Model CT4810 (CT5880 chipset). See what this comes back with; asoundconf list eg; [EMAIL PROTECTED]:~# asoundconf list Names of available sound cards: V8237 Intel Ubuntu seems happy to find the SOLO-1, but no immediate sign of the Creative. I'm off to find a Howto right now, but some guidence would be appreciated Perhaps you could have a look at the output of 'lspci'. You should have a at least two entries for you sound cards, ie, one each. eg; [EMAIL PROTECTED]:~$ lspci :00:00.0 Host bridge: VIA Technologies, Inc. VT8378 [KM400] Chipset Host Bridge :00:01.0 PCI bridge: VIA Technologies, Inc. VT8237 PCI Bridge :00:06.0 RAID bus controller: 3ware Inc 3ware 7000-series ATA-RAID (rev 01) :00:07.0 Ethernet controller: Intel Corp. 82546GB Gigabit Ethernet Controller (rev 03) :00:07.1 Ethernet controller: Intel Corp. 82546GB Gigabit Ethernet Controller (rev 03) :00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01) :00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller (rev 60) ... anyhow you should have an entry for each sound card. perhaps your sound cards are sharing an interrupt and they don't like that ... with a bit more info you should be able to track down if you can't see the second card and why, then fix it ;) cheers, Kim -- vk5fnet -- ubuntu-au mailing list ubuntu-au@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-au
