The graphics card isn't showing up, though it did appear before.
Ubuntu 14.04 LTS, fully updated and UtD. Server setup uses a Dell Poweredge 2900(iii) with an integrated ATI ES1000 (cannot disable). Initially, I had an x8 PCIe GT 730 in. The system would start with the ATI chip, reach the encryption unlocking code, and after success, the GT card would take over—everything works fine so far. Recently, I upgraded to an ATI Radeon 4770, cut it down, connected power cables, and swapped the GT card. Booted successfully; first the built-in card loaded, then the new one took over. However, no GFX acceleration appeared. A forum post suggested uninstalling the nVidia driver, rebooting, and installing the ATI (fglxr) version—this aligns with removing the old card. After clearing nVidia-related files, rebooting, installing the ATI driver, and restarting, the system recognized the new card but still didn’t load properly. Programs like Sysinfo only detected the ES GFX chip. I’m unsure what to do next; I’d rather not wipe and reinstall since I have many files here, but I’ll consider it if necessary.
Suggestions:
- Check if the ATI driver actually communicates with the Radeon GPU.
- Verify that the nVidia chip is still present in the system (lspci output).
- Try reinstalling the ATI driver without removing the original card.
- If issues persist, consider temporarily using a virtual display or alternative graphics mode.
The issue arises because the system attempts to set up both ATI cards, which may be incompatible. The driver doesn’t know what to do and simply fails. I faced a similar problem when trying to use my onboard GPU (an older AM3 model) with the 7770. The driver wouldn’t install unless I removed the 7770 or turned off the onboard GPU, after which it couldn’t handle both devices. It seems the driver made unexpected changes and installed the ES1000 driver without properly setting it up.
The driver likely grabbed the integrated GPU first, while the NVIDIA driver detected just one card. Consider using an open-source alternative.
Seems like you were double-checking something but might have missed it. Let's give it another shot tonight.
