Public bug reported: Binary package hint: xorg
Hello, Summary ------------ Using ATI radeon driver leads to a blank screen when my screen is connected with DVI. RadeonHD driver used to work perfectly until I switch to Ubuntu 10.10 where it is no more supported. Configuration ------------------- % lspci 01:00.0 VGA compatible controller: ATI Technologies Inc RV610 video device [Radeon HD 2400 PRO] ... It's a card with a VGA and a DVI output. My monitor is a Samsung SyncMaster 2232bw. Its native resolution is 1680x1050 Details ---------- I just switch to 10.10 and discovered that the radeonhd driver is no more supported. Problem: the "radeon" (or "ati", as it's the same) driver does not work well for me: - if I use the DVI output, I just get a blank screen - with the VGA output, I get a really *really* bad image, difficult to describe: its blurred, or with kinds of waves, as if there was a lot of interferences. It's almost not usable at 1680x1050, better at lower resolutions Changing from KMS with radeon.modeset=0 has no consequence. Trying to not use EDID information (Option "IgnoreEDID" "true") leads to same result. Fglrx does not work either, at 1680x1050 I get a "flashing" image (screen goes blank every 2 seconds or so), and at lower resolution the screen is flashing (but less frequently) "Vesa" driver works perfectly, both on VGA and DVI, but I can not use 1680x1050 with them, only 1280x1024 (what is expected with vesa driver). It uses to work perfectly at 1680x1050 with radeonhd driver. If I switch my screen for my TV (connected in DVI) with the radeon driver, I get an image in full HD. So, it seems that there is something wrong with either my card, the screen, or the combination of the two. But for now, with Ubuntu 10.10, I have no solution to have a clean display at my screen native resolution.
