[SLUG] Mounting folders read only
Hey guys, Im hoping this is a simple one (however too complicated for me). Is there anyway I can mount a folder read only just as I would if it were a separate partition? e.g. mount /home/foo readonly even though its part of /dev/hda1 which is read-write Any help would be appreciated..

[SLUG] Reading DVDs
Hi, I bpought myself a Ricoh RW5240, upgraded it to the latest firmware, and stuck it in a USB case. This works with Linux 2.6.13 and the usb-storage drivers. However, every now and then, a DVD which I could read perfectly last time I used it refuses to be read by this combination, although it reads perfectly on my wife's Powerbook. Does anyone have any idea what's going on? Is this drive particularly sensitive to dirt and scratches? Or is the USB driver in Linux particularly bad at recovering from errors? The kinds of things I see are: (after dd if=/dev/sr8 of=/dev/null bs=32k) ... usb-storage: Attempting to get CSW (2nd try)... usb-storage: usb_stor_bulk_transfer_buf: xfer 13 bytes usb-storage: Status code 0; transferred 13/13 usb-storage: -- transfer complete usb-storage: Bulk status result = 0 usb-storage: Bulk Status S 0x53425355 T 0x2b R 32768 Stat 0x1 usb-storage: -- transport indicates command failure usb-storage: -- unexpectedly short transfer usb-storage: Issuing auto-REQUEST_SENSE usb-storage: Bulk Command S 0x43425355 T 0x802b L 18 F 128 Trg 0 LUN 0 CL 6 usb-storage: usb_stor_bulk_transfer_buf: xfer 31 bytes usb-storage: Status code 0; transferred 31/31 usb-storage: -- transfer complete usb-storage: Bulk command transfer result=0 usb-storage: usb_stor_bulk_transfer_buf: xfer 18 bytes usb-storage: Status code 0; transferred 18/18 usb-storage: -- transfer complete usb-storage: Bulk data transfer result 0x0 usb-storage: Attempting to get CSW... usb-storage: usb_stor_bulk_transfer_buf: xfer 13 bytes usb-storage: Status code 0; transferred 13/13 usb-storage: -- transfer complete usb-storage: Bulk status result = 0 usb-storage: Bulk Status S 0x53425355 T 0x802b R 0 Stat 0x0 usb-storage: -- Result from auto-sense is 0 usb-storage: -- code: 0x70, key: 0x5, ASC: 0x64, ASCQ: 0x1 usb-storage: Illegal Request: Invalid packet size usb-storage: scsi cmd done, result=0x2 usb-storage: *** thread sleeping. end_request: I/O error, dev sr8, sector 0 -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

[SLUG] Two problems - any CLUE/LART accepted
Hi All, From the coercion of a colleague (hi Mike), I've done the Quake3 thing - something I've always resisted. I'm not a big FPS fan, RTS is more my thing, but anyway. The hardware: My system is a K8VSE-Deluxe AMD64-3000+ machine with an NVidia FX5700 card with TwinView (dual head) set up and working nicely with KDE. First Problem: Whilst hacking the bejeezus out of the Q3 installer to handle my AMD64 Kubuntu system, I realised the DVD-ROM has stopped running in DMA mode (WTF?). It used to, but I haven't used it in over 4 months and I think there was a kernel update in there somewhere. I've done the hdparm -d1 /dev/hda but it just barfs and syslog dumps a Drive Seek Error 0x51 etc in dmesg (yes, hda, my SATA drive is the boot drive and is sda). Any ideas? I'm not in front of my AMD64 box so chipsets/exact-errors will come laterjust thought someone might have seen this before? Second Problem: After getting Quake3 running (yay me...I think) I have it displayed on the second monitor (on the right) in the bottom-left corner with only the top half of the image displayed (see ASCII art below). My primary monitor runs 1280x1024 and the secondary runs 1024x768 with TwinView handling all the multi-head stuff. Obviously 1/2 of a Q3 screen aint gonna get me anywhere so how can I force it onto the main dislpay at a reasonable resolution? eg, - | | | | |This is all black | | | Primary monitor is over there -- | | and is totally black. | Quake 3 | | | top 1/2 | | | here | | - Ideas anyone? I need dual head more than I need quake, but it would be nice not having to boot that other OS just for the occasional fragging.

You could run in windowed mode, if you can see enough of the settings menu, uncheck 'full screen', or hit alt-enter. I have seen Q3 display strangely if it's told to run in a resolution not actually listed in xorg.conf, have you tried setting Q3 resolution to 1024x768? If it runs OK apart from all that, can you let me know what nVidia card you're using? I have plain Ubuntu on AMD64, but 32 bit games run at a fairly bad framerate and have glitches with textures displaying strangely. eg, - | | | | |This is all black | | | Primary monitor is over there -- | | and is totally black. | Quake 3 | | | top 1/2 | | | here | | - Ideas anyone?
